fix(fixer): restore the addition of the GitModified filter option

[valeryan]

Not sure if it was correct to remove the filter. I need to test if its correct to use git modified here or remove and cleanup document range.

The logic for git modified was added here: https://github.com/valeryan/vscode-phpsab/pull/54 This logic was removed here: https://github.com/valeryan/vscode-phpsab/pull/55/files#diff-8252e32d33853b0c73ac8a3449d744d96025b7aa6926201d9ae16c4a6d3c079bL113

But did I remove it by mistake or for reason? The world may never know.
