Remove Emacs spam

My inconsistent git history-keeping is coming to bite me here. At the
moment, I can only speculate about what went wrong here. The gist is
this: I unintentionally committed files that were supposed to be ignored

This commit removes those files which includes:

- auto-save-list
- elpa packages
- quelpa packages
- misc

configs/shared/emacs/.emacs.d/wpc/packages/wpc-docker.el
