This was added during the conversation to a service class in commit5a6c18a086(Iaa7354f31), but the code it was for is unused and was shortly after removed in commit37022e2e(Ifa00c59ab), thus leaving this unused dependency behind. The motiviation for this change is that Parser is used during the installer (maintenance/install.php) with DB services naturally disabled, and Parser has the dependency chain Parser -> BadFileLookup -> RepoGroup (hidden) -> FileBackendGroup -> LockManagerGroup. Solving the hidden part is proposed in I9de42a26cd, but fails as LockManagerGroup currently depends on LBFactory which makes it crash in db-less environments.
