Enable TLS test for all URLs by default in baseline

The Alexa top 500 list has domain names that have TLS enabled, but the TLS test doesn't test them given that the https:// is missing from the URL in that list. TLS can be enabled by default for all URLs to check for and test TLS.

I have added the option to do this, but it will slow things down when testing larger URL lists.
I'm not really sure if this should be enabled for all of our test lists. Instead, I think sanitizing URL lists to include protocol types is a much better idea.
