Remove unneeded quotes from autocomplete % nodes

[aXu-AP]

Removes unnecessary quotes for suggestions like $"%MyNode".

The change makes sense and works. Could you maybe add a test case for it?
You could put it in here: https://github.com/godotengine/godot/tree/master/modules/gdscript/tests/scripts/completion/get_node/

I tried to add a test, but I'm not sure if I did it right and if the location and name makes sense. For some reason I can't run tests locally (I did build with scons dev-mode=yes, dunno why it doesn't work)...

The test looks good to me and passes in CI, so you did it right 🎉

LGTM (still needs an official review though)

[aXu-AP]

Thanks for reviewing and also for your work with autocompletion, I think it's the feature that makes or breaks the code editor 👍

By the way, do we have existing test case for $ operator's autocompletion? For basic case ($ -> SomeNode) and for quotes ($ -> "Other Node")? I didn't find them... I could add them here if they don't exist yet.

I was looking for some when I tried to link you to a location to add them and didn't find something. That being said, I'm currently changing something about the test runner, tests will probably be compatible but I wouldn't invest time into it before the new behavior is in.

[aXu-AP]

Gotchu. If you want, CC me once the changes are in, I can do it afterwards :)
