uBO will now verify that at least one unprocessed network requests
at launch should have been blocked in order to warn users of
unprocessed network requests through the `!` toolbar icon badge.
For example, with default filter lists, there is nothing to block
on `wikipedia.org`, and hence in this case it's not useful to
present the user with the `!` badge.
Therefore uBO will not show the badge *only* when at least one
unprocessed network requests should have been blocked had uBO been
ready when it was fired by the browser.
