The threading tests currently wait for a very small amount of time for
the expected test condition to be reached, e.g. 20ms. This changes the
tests to *check* the condition every 20ms, but allow the test to run for
up to 2s until the condition is reached. This should hopefully resolve
the failures seen on CI.
This also renames one of the tests to match what it actually does. The
test itself was changed in commit 5b335e7, but the name was not updated
to reflect that change.
Note that in some cases (in particular SQL::Result and PDFErrorOr),
there is no Formatter defined for the error type, hence TRY_OR_FAIL
cannot work as-is. Furthermore, this commit leaves untouched the places
where MUST could be replaced by TRY_OR_FAIL.

Using a file(GLOB) to find all the test files in a directory is an easy
hack to get things started, but has some drawbacks. Namely, if you add
a test, it won't be found again without re-running CMake. `ninja` seems
to do this automatically, but it would be nice to one day stop seeing it
rechecking our globbed directories.
