msc: add test for OS#5532: crash from CM Serv Rej

Reproduce the assertion trigger crashing osmo-msc reported in OS#5532,
i.e. a CM Service Request that contains a mismatching Mobile Identity.

Causes osmo-msc to crash with an assertion, so run it last.
Fix of the crash: I6c735b79b67108bcaadada3f01c7046e262f939b

Related: OS#5532
Depends: I6c735b79b67108bcaadada3f01c7046e262f939b (osmo-msc)
