f_tc_ho_out_fail_no_ho_detect: stricter ordering

Make sure that the RR is released only after the MSC has sent the Clear Command:
- first expect a Clear Request from osmo-bsc and return a Clear Command,
- only then accept RR release messages.

See 3GPP TS 48.008 3.1.5.3.3 "Abnormal Conditions": "The terrestrial resource
in the old BSS shall remain assigned until a CLEAR COMMAND message is received
from the MSC"

osmo-bsc already complies, the test should continue to pass.
