Title: Adding handling for upper case drive letter in Windows

The check fails when the path starts with a Windows letter drive that’s
upper case, causing the path to then include the currentDirectory.
This fails when a rootPath is specified along with an import statements
like:

@import url("brackets_colors.less");
