Jehan abf66dd66a plug-ins: prevent explicit http scheme to be automatically changed to https. 
This completes commit 685c8bde99 where the http:// scheme was automatically
transformed into https:// in some cases, in particular while typing (when
pasting for instance, it was still possible to add an http URL). So let's block
"toggled" signal handlers when the URL is explicitely edited to prevent this
annoying issue.
