[issue3323] import --no-commit creates a repository transaction

[roman-neuhauser]

New submission from roman-neuhauser <neuhauser at sigpipe.cz>:

rollback after import --no-commit reports rolling back the import.  import 
--no-commit should not create a repository transaction: it does not clobber 
the repository.

the test case is attached.
