drive: Make FileCache::RenameCacheFilesToNewFormat responsible to canonicalize file name
Move file name canonicalization responsibility from CanonicalizeIDs to RenameCacheFilesToNewFormat CanonicalizeIDs will be deleted soon when cache entry ID canonicalization code moves to ResourceMetadataStorage. BUG=309597 TEST=unit_tests R=kinaba@chromium.org Review URL: https://codereview.chromium.org/32333002 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@230029 0039d316-1c4b-4281-b951-d872f2087c98
