Unregister all scriptlets when disabling uBO on a specific site 

Related issue:
https://github.com/uBlockOrigin/uBlock-issues/issues/3083

This will not completely eliminate the issue but it should
lower the likelihood it will occur -- so at least uBO can
still benefit from reliable scriptlet execution in Firefox.
