Check for failures in base SetUp()

If the base set up fails, the RKP version number might not be valid so
we shouldn't try to work out whether the test should be skipped based on
the version.

Assert that there weren't any fatal errors from the base set up rather
than reporting that the test should be skipped as that can be a bit
confusing.
