BSC_Tests: fix TC_ciph_mode_a5_{0,1,3}

The helper function f_tc_ciph_mode_a5(), thich performs all of the
three tests currently disables the ASSIGNMENT COMMAND since due to
a bug in OsmoBSC a MODE MODIFY would be attempted by the BSC,
causing the testcase to fail.

The problem in OsmoBSC is now fixed and the ASSIGNMENT COMMAND can
be re-enabled again for this test. However, the test function
includes and expects an AoIP transport layer address, which is
not included for signalling assignments.

- Make sure no AoIP transport identifier is included in ths
  ASSIGNMENT COMMAND

- Do not expect an AoIP transport identifier in the
  ASSIGNMENT COMPLETE from the BSC

- Re-Enable the generation of the ASSIGNMENT COMMAND
