Fix testTtffWithNetwork timeout issue

There is no NLP in GSI project, but case testTtffWithNetwork still wait 2 minutes
for network location. This flow will run twice so waste 4 minutes of waiting time,
it's easy to cause case 5 minutes timeout failure.
Do not waiting for network location result if there is no NLP.
