bsc: fix ho-out test failures: cleanup neighbor cfg cruft 

In the out-of-this-BSC handover tests, a neighbor config of LAC 99 left
behind from a previous test obstructed the test from working:

 % BTS 0 already had neighbor LAC:99 ARFCN-BSIC:123-45
 % ERROR: duplicate Cell ID in neighbor config, with differing ARFCN+BSIC: LAC:99 ARFCN-BSIC:123-any

Add a 'no neighbor lac 99' before configuring the neighbor via VTY.

Also add the missing neighbor config to
f_tc_srvcc_eutran_to_geran_ho_out_main().

Affects tests:
BSC_Tests.TC_ho_out_of_this_bsc
BSC_Tests.TC_srvcc_eutran_to_geran_ho_out
BSC_Tests.TC_srvcc_eutran_to_geran_ho_out_forbid_fast_return
