Fix snap unset

[sklassen]

Overview

snap set couchdb name=xxxx corrupts vm.args.

Since needing to handle # - setcookie the commented # -name=examples are also caught by regex.

Testing recommendations

Tested twice with when vm.args

# -cookie -cookie xxxx

sudo snap set couchdb-sklassen setcookie=cutter sudo snap set couchdb-sklassen name=couchdb1@127.0.0.1

Related Pull Requests

Handle the commented and not commented vm.arg changes separately.

I have also unset the variables after config changes. This speeds up snap set as previously set variables no longer requires changing the file a second time.
