Incorrect implicitly label for partial files

[mrmlnc]

• VS Code Version: 1.40.2
• SCSS IntelliSense Version: 0.8.1+
• Operating System: Windows

Reproducible Case:

// _provider.scss
@mixin gradient-striped($color: rgba(255, 255, 255, .15), $angle: 45deg) {
  background-image: -webkit-linear-gradient($angle, $color 25%, transparent 25%, transparent 50%, $color 50%, $color 75%, transparent 75%, transparent);
  background-image: -o-linear-gradient($angle, $color 25%, transparent 25%, transparent 50%, $color 50%, $color 75%, transparent 75%, transparent);
  background-image: linear-gradient($angle, $color 25%, transparent 25%, transparent 50%, $color 50%, $color 75%, transparent 75%, transparent);
}

.test1 {
  @include gradient-striped;
  background-size: 40px 40px;
}

// test.scss
@use "provider" as p;

.test2 {
  @include p.gradient-striped;
  background-size: 40px 40px;
}

Steps to Reproduce:

1. Open the test.scss file;
2. Hover the gradient-striped node; The lettering would be @import "_provider.scss";; Go to the definition;
3. Save the _provider.scss file;
4. Back to the test.scss file
5. Hover the gradient-striped node; The lettering would be @import "_provider.scss"; (implicitly);

We need to use ls.findDocumentLinks2 to fix the problem at the root. To do this, we must switch to the URI instead of the paths in the providers, parser and scanner.

Must be fixed by 0.9.0.
