Go to definition from template not working when update to vetur 0.28.0.
Work just fine when downgrade to 0.27.3

Reproducible Case

In VS Code with vetur 0.28.0, hover any variable or function, Ctrl + click won't go to definition, instead show this error in the bottom right in vscode window

_Temporary solution_: Downgrade vetur back to 0.27.3

I'm having the same problem (using Vetur 0.28.0 on Windows 10).

When I click "Go to definition", Visual Studio closes the file I am working on, and displays a message "unable to open 'file.vue': Unable to resolve resource (path)"
I noticed that the path contains forward slashes (e.g. c:/path/to/file) instead of the usual convention on Windows of using backslashes (c:\path\to\file). I don't know if that's significant.

I think this might be the same problem as issue #1484, which was fixed in #2161
I believe it was caused by path handling inconsistencies between Windows and Mac/Linux.

2161 updated server/src/modes/template/interpolationMode.ts, by wrapping 2 uri's in URI.file

I have just checked the latest version of interpolationMode.ts, and the calls to URI.file have been removed, which could explain why the problem has resurfaced.
