Merge lp:~jelmer/bzr-builddeb/552893-fix-upstream-tarball into lp:bzr-builddeb

[Jelmer Vernooij]

This fixes the "assert path is not None" error (or at least one of its instances).

GetOrigSourceSource would happily claim success in some situations, because it only raises RevisionNotPresent when _get_orig_source() returns None, not when it returns False.

This would then cause provide_from_store_dir() to not be able to find the upstream tarball, and return None.
