I dislike the "fixture" style of testing -- it makes it non-obvious what tests do, because they have hidden behavior without even an obvious function call you can trace through. Can we stick to the existing style?

Was there a reason this was skipping Debug severity before?

Not really; we aren't using Debug much. I changed the logging of one expected message from Debug to Info since it was a better fit anyway.

When does this situation arise? Do we not want it to be considered a logic error, and require the database to outlive any transactions?

Please re-review; I split up all of the commits to make them easier to review. I removed the common base class for tests, and they now explicitly perform all preparatory actions in each test body. |

// Newly created database, or old cache-only database; remove old table if it exists.
Before this change, we've tried to open the database in read/write, but not create mode. In situations where the database didn't exist yet, this logged an error to the console, and we proceeded to opening it again in read/write/create mode, which actually created the file. The reason we did this is so that we could detect really old caching databases from January 2016 in case a developer upgraded from an older SDK (iOS v3.1 and earlier, Android v3.2 and earlier) that didn't have #3715 yet. However, these error messages, while innocent, look scary in the console and some users suspect that it's a bug. This change opens the file directly in read/write/create mode, omitting the first failed attempt. To handle old cache databases, we're now deleting the `http_cache` table, which was the only table in those old databases, and create the new schema, rather than deleting the entire file and recreating the Database object. In most scenarios, this will lead to one fewer opening attempt, while the database migration will continue to work for the few users who upgrade all the way from a January 2016 SDK. Additionally, this fixes a mismatch between the Qt and non-Qt implementation: Qt doesn't support opening a file in read/write mode without the create flag. This means that we've seen a different control flow on Qt compared to the non-Qt implementation when opening a database.
