Fix an issue with Multi-folder workspaces

[silenceisgolden]

There may be some issues with this PR:

• I do not know why it saved the full file again. I do have CRLF selected in VSCode. Maybe it is the incorrect line in .editorconfig that should be changed such as indent_style = 2 -> indent_style = tab?
• I am not sure how to mock a vscode.TextDocument in order to test the method. I am happy to add tests though if you can point me in the right direction on mocking.

Looking through the vscode api for getWorkspaceFolder and workspaceFolders, this looks perfect to me @silenceisgolden.

I agree, the whole file changing could be related to tabs vs. spaces. I didn't even realize that value was set incorrectly. This has been updated. Feel free to merge latest into this branch.

I wouldn't worry too much about the testing aspect. It's a very minor change, the extension itself is pretty small, and the core logic is based around parsing errors which already has tests for it.

If you want to update the PR such that only the single line is modified, I'll go ahead and merge it in and cut a new release with this fix.

Much appreciated! 💯

@jpreese Updated, and commits squashed.

Turns out on Mac's trying to preserve CRLF, users need to set git config --global core.autocrlf true on their local.

Oof, good catch! Thanks for fixing this. I'll add it into the next release.
