BSC_Tests: Change test-expectation of TC_paging_resp_unsol

The testcase TC_paging_resp_unsol expects the BSC to close the channel
when an unsolicit paging response is received. This expectation is due
to the fact that osmo-bsc supports multiple MSC, which is not specified
in 3gpp specs. Therefore the BSC needs to know which MSC is in charge.

However, with MT-CSFB calls it is a normal situation that the BSC
receives a paging response on abis without sending a paging first since
the MSC has paged the UE via the SGs interface. In those cases we expect
the BSC to forward the paging response to the first configured MSC.
