Title: FIXED: Issue with test reporting

In the case of errors arising during setUp or setUpOnce a unit test will fail to run any individual tests. However, this situation was incorrectly being reported as a test pass (as no tests were run, thus no tests had errors). E.g. the output of a test run that raised an error during setUp would be "0 tests run: 0 passes, 0 failures, and 0 incomplete" with a green background.

To rectify this the following fixes were made:
- Non-cleanly ended tests and test suites are now automatically ended at the end of the test run, as well as at the beginning of subsequent test/suites. This should make catching of errors a lot more robust.
- Errors raised during setup are now no longer lost to the mist of time. The test suite itself will record any error status which was generated outside the scope of any individual tests.
- An additional "errors" count is added to the output at the end of test running. For example, in the case where setup failed and no tests could be run the error would be written to the browser (along with stacktrace) with a message similar to "0 tests run: 0 passes, 0 failures, and 0 incomplete with 1 errors". The intent of this is to separate the concepts of failed/succeeded/incomplete tests from any errors which may have arisen. I.e. no tests "failed" due to the error, but the test run itself is highlighted as an error (red background on the output).

This problem has been a severe cause of issue when testing code that interacts with the database, as any database error during setup would refuse to be shown.
