Do not call Diff Cache when not needed
ApprovalInference now calls DiffCache (patchList). This is an expensive
operation, which should only be called whenever really necessary. This
is unfortunately needed when computing whether we can copy over labels
if there is a label that is configured not to copy over if the list of
files didn't change.
