Subject: [PATCH] Don't Rely on LSP Client to Init Maps

This commit makes sure that clients who send minimal data in the
initialize options cause some NullPointerExceptions (as reported in
sonarlint.nvim issue #35:
https://gitlab.com/schrieveslaach/sonarlint.nvim/-/issues/35). Also,
this commit restores the previous behavior to automatically analyze
files that are open in the editor.
