tcap routing doesn't work the way the test thinks. E.g. a Begin can't be routed to a special destination because it does't contain a dtid which is needed to route to the correct ASP.
STP_Tests_TCAP: Test routing of fragments in TC_tcap_loadshare_ipa_tcap_range_success_pc
A TCAP Begin will cause the stp to create a cache entry and route according to that. Send only a TCAP Continue so we check the tcap range routing logic.
