Fix solidfire unit tests

A couple of tests attempted to reimplement assertRaises(), but did so
badly. self.fail() will raise AssertionError, which is a subclass of
Exception, so even if the tested exception wasn't raised, it would
silently treat it as a success.

This buggy testing code hid a failure to properly test the intended
functionality in test_delete_volume_fails_no_volume.
