Empty acq_time results in empty cell not 'n/a' #390

BIDS validator gives me this error for acq_time: [ERR] Empty cell in TSV file detected: The proper way of labeling missing values is "n/a"

This is because str(None) in Python gives 'None' which has True boolean value. Fortunately, the fix is simple.

for cases where the field exists but is empty

This is largely a bug fix.  Metadata and order of `_key-value` fields in BIDS
could change from the result of converting using previous versions, thus minor
version boost.

 Enhancement

- Use [etelemetry](https://pypi.org/project/etelemetry) to inform about most
  recent available version of heudiconv. Please set `NO_ET` environment variable
  if you want to disable it ([#369][])
- BIDS:
  - `--bids` flag became an option. It can (optionally) accept `notop` value
    to avoid creation of top level files (`CHANGES`, `dataset_description.json`,
    etc) as a workaround during parallel execution to avoid race conditions etc.
    ([#344][])
  - Generate basic `.json` files with descriptions of the fields for
    `participants.tsv` and `_scans.tsv` files ([#376][])
  - Use `filelock` while writing top level files. Use
    `HEUDICONV_FILELOCK_TIMEOUT` environment to change the default timeout value
    ([#348][])
  - `_PDT2` was added as a suffix for multi-echo (really "multi-modal")
    sequences ([#345][])
- Calls to `dcm2niix` would include full output path to make it easier to
  discern in the logs what file it is working on ([#351][])
- With recent [datalad]() (>= 0.10), created DataLad dataset will use
  `--fake-dates` functionality of DataLad to not leak data conversion dates,
  which might be close to actual data acquisition/patient visit ([#352][])
- Support multi-echo EPI `_phase` data ([#373][] fixes [#368][])
- Log location of a bad .json file to ease troubleshooting ([#379][])
- Add basic pypi classifiers for the package ([#380][])

 Fixed
- Sorting `_scans.tsv` files lacking valid dates field should not cause a crash
  ([#337][])
- Multi-echo files detection based number of echos ([#339][])
- BIDS
  - Use `EchoTimes` from the associated multi-echo files if `EchoNumber` tag is
    missing ([#366][] fixes [#347][])
  - Tolerate empty ContentTime and/or ContentDate in DICOMs ([#372][]) and place
    "n/a" if value is missing ([#390][])
  - Do not crash and store original .json file is "JSON pretification" fails
    ([#342][])
- ReproIn heuristic
  - tollerate WIP prefix on Philips scanners ([#343][])
  - allow for use of `(...)` instead of `{...}` since `{}` are not allowed
    ([#343][])
  - Support pipolar fieldmaps by providing them with `_epi` not `_magnitude`.
    "Loose" BIDS `_key-value` pairs might come now after `_dir-` even if they
    came first before ([#358][] fixes [#357][])
- All heuristics saved under `.heudiconv/` under `heuristic.py` name, to avoid
  discrepancy during reconversion ([#354][] fixes [#353][])
- Do not crash (with TypeError) while trying to sort absent file list ([#360][])
- heudiconv requires nipype >= 1.0.0 ([#364][]) and blacklists `1.2.[12]` ([#375][])
