tests: Make P2PS join-a-group cases more robust

Use the group SSID (if known) when requesting a join operation. This
makes some of the P2PS test cases more robust in cases where previously
executed tests have added older groups into the cached scan results with
the same MAC addresses and an incorrect BSS could have been picked
previously.
