nvim: plugins: Remove auto-session

Recent changes to auto-session which got added with session lens
support are just plain annoying. It adds telescope support which
broke session loading as we do not use telescope. It has started
creating session files which we do not want and there seems to be
no setting to disable them or at least if there is it is not at
all obvious from the documentation. Just nuke this nonsense.
