Don't replace the outline view until completion

[envygeeks]

I am using the latest version of:

• Atom
• ide-go
• atom-ide-ui
• go-langserver

Right now your software replaces the outline view well before the outline is finished, which means if there is an error in the software, you've cleared out the view, and getting to a point in the source where it's easy to find the error is ultimately harder.
