bsc: make ho_config_tests more robust against timing
In f_probe_for_handover disable the RSL emulation before the vty handover command. Otherwise, osmo-bsc may be too fast to issue the handoverCommand, so that RSLem still handles it and says: "RSL for unknown Dchan". (f_probe_for_handover() receives the handoverCommand directly, just to detect whether a handover would be initiated, and then quickly aborts the handover procedure.)
