bsc: Fix race condition exiting f_ho_out_of_this_bsc 

The function didn't wait to receive the 2 messages from the BSC. As a
result, they may have arrived while tearing down the test components
shortly after exiting the function and provoke a Dynamic Test Error
while pushing the messages up the stack since some of the stack layers
may already be unavailable.

Test TC_ho_out_of_this_bsc() workarounded this by using a f_sleep(1),
but TC_srvcc_eutran_to_geran_ho_out() didn't, making it fail sometimes.
