fix(egdy): do not add panes for not enabled neo-tree sources (#3667)

## What is this PR for?

When the user disables a specific neo-tree source (git_status or
buffers), the panes are still created but throw an error when the user
tries to open them

**NB**: This is currently not functional because `LazyVim.opts` is
returning an empty table instead of the neo-tree opts. I'm hoping
someone can give me a hand with this little problem
