Add manual check before starting mutationObserver

Sometimes, when starting the mutationObserver, watched nodes have
already been added and are therefore not detected.

This change is a follow-up change to change
https://gerrit.avm99963.com/c/infinitegforums/+/1041 which fixes the
same thing for the mutationObserver at
//src/content_scripts/console_inject.js.
