gbproxy/test: Add a test with a P-TMSI collision between two SGSNs
This patch extends test_gbproxy_secondary_sgsn() by the establishment of a third MS connection using a P-TMSI that has been assigned by the other SGSN already. It is expected that the entries do not interfere and are properly retrieved. Note that these collisions are not handled properly yet. Sponsored-by: On-Waves ehf
