Postponing taking bugreport until after the time-limited art of the test.

Disabling bugreports resulted in reducing TestTimedOutException
rate from 98% to 78%, but didn't change other timeout-like exceptions.
So, can restore taking bugreports in general, but in in cases where they'd
result in TestTimedOutException.
