Description

I can't seem to have an outline for .vue files and there is no autcomplete available. I'm not sure if I need to install a separate package for autocomplete but I'm interested in the outline anyway. This is the console output at the start of atom. Made it as simple as possible by disabling as many packages as I can.

Steps to Reproduce

1. Purge the existing atom installation:

sudo apt purge atom
rm -rf ~/atom
rm -rf ~/.atom
rm -rf ~/.config/Atom

3. Download and install a fresh atom using https://atom.io/download/deb.
4. Install packages atom-ide-vue, language-vue, atom-ide-base and atom-ide-ui (to be able to see the console). At this point atom tells us we have two packages that do the same thing: linter and atom-ide-diagnostics and asks if we wanted to remove one of them. Politely decline. Then restart the ide for good measure. This is where we're at:

$ apm ls -id

6. Add a project folder with a .vue file in it and open the file. Double check if the file is detected as a Vue file. Check if another option for a .vue file is listed. Everything should be in order. The outline view is completely empty. As in no messages about not having an outline either.
7. Open the console and see the error message (along with some other messages about the error message):

Expected behavior:

Having the proper outline for the file and no errors in the console.

Actual behavior:

No outline what so ever. Not the generic empty outline message either. Just the filter bar and that's it.

Reproduces how often:

Every single time consistently.
