Catch InconsistentAnalysisException in getParsedUnit() in server.

I see this exception happening in google3, probably because users
change this or other files, or watch events happening, or open / close
(maybe?) files. Anyway, this something that may happen, and the server
should handle it.

The way this CL handles it maybe not the best. By returning `null` we
basically fail the request - sometimes return `Response.fileNotAnalyzed`,
sometimes return empty results. We could retry, nad hope that no
file changes will happen next time. Or another next time, etc.
