Revert "Possible fix for copy text not working"

This was causing problems pasting into dev tools on OS X.  It was
originally done to see if it would get past the intermittent copy/paste
problem and it didn't.

This reverts commit bf04711.

Register filters for private tabs lazily

Hypothesis is that there is some sort of race condition at startup
leading to filters not being registered in private tabs about half the time (brave#970). Since filters seem to always be registered in session tabs,
register for private tabs in the same way.

Return null redirectURL for HTTPS Everywhere excluded URLs

When redirectURL is set to the original URL, this can cause the browser to throw
net::ERR_TOO_MANY_REDIRECTS and not load the URL. Caused foxnews.com to break.
