tests/qtest/migration: Replace connect_uri and move migrate_get_socket_address inside migrate_qmp

Browse Source 
Move the calls to migrate_get_socket_address() into migrate_qmp().
Get rid of connect_uri and replace it with args->connect_uri only
because 'to' object will help to generate connect_uri with the
correct port number.
