LSP: Fix Ctrl + click underline highlighting broken in #include context

Currently if you ctrl + click in a #include <some/file.h> context, you get underline under "some" or "file" and not even "file.h" which makes it look very weird and as if "some" is something else and "file.h" is something else, when in fact they form one thing and point to one thing. This change fixes this by expanding the range to include everything between <> or "".
