error accumulating test counters in frontend

[maormarcus]

When running a session with interrupted test, this test can also have errors.
In this case both session.num_error_tests and session.num_interrupted_tests incremented.
This causes the session.num_successful_tests to be wrong.

@vmalloc Any suggestions?

Perhaps we can have a boolean field for tests called "counted", defaulting to NULL to save on the migration time. Operations attempting to increment the counters for the session will only do this if this field is false, and then set it to true?

@vmalloc I think you want to count both interruptions and errors (for example, if test had error and interrupted afterwards - you want it to be shown in session view).
Maybe adding to the session model num_successful_tests and in report_test_end update it as well?

That's possible... the only problem is that after this change previous runs would show incorrectly...
