[VOL-4318] check correct indication of abort download

Further corrections:
Reset BBSIM in Teardown to make sequential running of SW Upgrade tests
possible. This makes bug [VOL-4262] as no longer needed.

Also deprecated keyword 'Restart Pod' is removed and all corresponding
test suites adapted accordingly.
