Simplifying drivers instanciation in tests

PEP8
Moving utility methods for testing drivers in drivers
Replace os.path with path.py in LocalStorage tests
PEP8: not in
Typo error message
Plug: Make sure that the entry is in the owners
Fix PEP8 nitpick
Add entry in 'uptodate' at the end of transfer
Save the metadata at the end of the transfer
Referee: Add uptodate to the should_own

When files in A are synced with B and a new file is created in A,
the Referee was not adding A in the new owners. Now the files that
are currently up-to-date are added by default.
This could cause a problem if the rule just changed, we should do
some experiments.
