Avoid moving DL-TBF from old_msg to new_ms during ms_merge
The DL-TBF assigned to another MS object may have a totally different
set of reserved resources (TS set, TRX, etc.), so one cannot simply move
those to the new MS. To start with, if the 2 MS are on different TRX it
is clear that one of them will not be really in operation. That's most
probably the DL-TBF being in ASSIGN state on CCCH waiting for PCUIF_CNF
and later X2002 to trigger to start sending DL blocks, but without
confirmation whether the MS is really there. Since the other new MS
object probably has a UL-TBF, that's the one probably operative, and
hence a new DL-TBF can be created at that same time and assigned through
UL-TBF's PACCH.
Unit test test_ms_merge_dl_tbf_different_trx showcases the above
scenario.
