Reset mode when changing buffers (#5072)
* Reset mode when changing buffers
This is similar to the change in
e4c9d4082a139aac3aea4506918171b96e81f5b9: reset the editor to normal
mode when changing buffers. Usually the editor is already in normal
mode but it's possible to setup insert-mode keybindings that change
buffers.
* Move normal mode entering code to Editor
This should be called internally in the Editor when changing documents
(Editor::switch) or changing focuses (Editor::focus).
