Check that module paths are directories before globbing them

I found that easy-install had added a .egg file to my python path, which then caused the language server to barf when it tried to glob "my_file.egg/**/whatever". This just adds an early return for when the path exists and is found to be a file in the two cases where it seems to matter.

I have no particular opinion. I'll leave it to the "vscode-ansible/ansible-language-server" team 🙇

Side note — @kimbernator you know that easy_install is at least half a decade deprecated thing with a lot of problems, right? Better not use it in the future.

@webknjaz Yep, not a concern. These files were just left over from running easy_install once or twice before understanding that it was deprecated. This still felt like a worthwhile addition in case other files work their way into that directory.
