Bug 29346: Use fully qualified names for C4:Circulation routines in C4::HoldsQueue

Bug 29346: Use fully qualified names for C4:Circulation routines in C4::HoldsQueue

I suppose this is similar to circular dependency on other patch

HoldsQueue uses Circulation uses BatchUpdateBiblioHoldsQueueuse HoldsQueue

Without this the background job builds the queue, but reports failure:
Holds queue for biblio The Jacobite clans of the Great Glen, 1650-1784 /. An error occurred (Undefined subroutine &C4::HoldsQueue::GetTransfers called at /kohadevbox/koha/C4/HoldsQueue.pm line 351. )
