Unit tests in miden-vm package are not running

[yasonk]

When running make test unit tests in the miden-vm package are not running.
For example:

miden-vm/miden/src/tools/mod.rs

Line 289 in fbce798

#[cfg(test)]

miden-vm/miden/src/cli/data.rs

Line 553 in fbce798

#[cfg(test)]

Here are some potential issues that don't seem to enable running the tests anyway:

1. Adding testing = [] to Cargo.toml
2. Renaming mod test to mod tests.

Adding unit tests to different crates of the miden-vm package also results in tests not getting run by make test.

I'm able to run the tests (when run some of the tests fail):

cargo test --package miden-vm --bin miden --features executable --  --show-output 

Should this be fixed by adding "executable" feature to make test, because it looks like the tests are skipped because the required-features in miden/Cargo.toml file lists "executable" in the [[bin]] section?
