Duplicate variable suggestion

[PixelT]

After enable extension I have duplicate suggestion for variable (see screenshot):

When I try to write variable from another file it's OK (I have only 1 item on list)
Duplicate value exist only when I declare & want to use variable in this same file.

Happens for me when the variables are defined in a separate scss partial file.

Will be fixed with #94. After that, we will exclude the local symbols (from the current document) from the hints.
