convert: update use of deprecated bzrlib property
The inventory property was deprecated in favor of root_inventory in bzr
2.5.0. Current version is 2.7.0.
I noticed this when testing locally on Python 2.6.9, which has warnings
turned on by default. The failure that occurs without this patch can be
seen on Python 2.7 by running with warnings enabled:
$ PYTHONWARNINGS=::DeprecationWarning make 'test-convert-bzr*'
