C#: Fix completion request with case insensitive resource path

Sometimes Visual Studio documents have the root path all in upper case.
Since Godot doesn't support loading resource files with a case insensitive path,
this makes script resource loading to fail when the Godot editor gets code
completion requests from Visual Studio.
This fix allows the resource path part of the path to be case insensitive. It
still doesn't support cases where the rest of the path is also case insensitive.
For that we would need a proper API for comparing paths. However, this fix
should be enough for our current cases.
