Fix for Bug#37766: Inserted review results.

Reason for the failing test was that "SELECT count(*) from mysql.general_log;" was not always
the same number. That was fixed by "...count(*)>4..." as the minimal fulfilled condition.
As Bug 35371 was fixed the testcase with "log_output = 'FILE'" was enabled and changed to have
always the same result.
