Completions not available for imported functions

[karthiknadig]

Repro steps:

• Clone the latest ptvsd project https://github.com/Microsoft/ptvsd
• Set PYTHONPATH to point to src
• Open up any file under pytests.
• Import and use any function from ptvsd, e.g, from ptvsd.socket import create_server, close_socket

Actual:
Get no completion. Sometimes you get name completions. Hover info is not available either.

Expected:
Should get completion

Probably should be resolved by #361 and related
