autotest: Make tast.py not write statuses for missing tests.

Make the "tast" server test avoid writing tests with missing
results to status.log. Missing results typically indicate
earlier DUT flakiness, and it can be confusing to report
that a test failed when it didn't even get a chance to run.

Also make the server test itself report failure whenever any
test results are missing or incomplete. This highlights the
underlying issue that needs to be investigated.

Finally, improve unit test coverage of messages attached to
TestFail exceptions (since these are displayed in builders).
