[Bug] Plugin skill autocomplete not working for invokable skills

Bug Description
When trying to invoke a skill installed via a plugin, the autocomplete doesn't work. You have to type out the complete skill name + namespace for the skill (if it's in a nested dir) without autocomplete, then it works. This is the case even when the 'invokable' option is set for the skill.
