Tons of errors about unexpected definition kinds during first analysis

[sfackler]

I'm using rls master (rls-preview 0.123.0-nightly (e0035b0 2017-11-07)), and seeing a couple thousand ERROR-level messages when rls first boots up:

This is on a decently large repo with rls in workspace mode.

I am seeing the same thing with a similar build with any repo. For example, running the RLS on the rls-analysis repo logs the same messages.
