[TYPO3-mvc] use of depreciated function

[Tim Schoch | GSTALTIG]

Hello

in 1.4.0-beta1 Tx_Extbase_Persistence_Query::withUid() is statet as
« @deprecated since Extbase 1.2.0; was removed in FLOW3; will be removed in Extbase 1.4.0; use equals() instead »
but it is still in the code and used from at least one point: Tx_Extbase_Persistence_Backend::getObjectByIdentifier()

Bug or with intent?
Tim
