Fix mis-handling of actual TLD in qIsEffectiveTLD()

If the domain passed down is an actual TLD that's the subject of a *
rule, e.g. "ck" subject to *.ck, then we were finding no dot in it and
concluding that it couldn't be the subject of a * rule.

Added a test for the specific .ck case and commented on where we could
get some canonical test data that I tripped over while researching
this. Cross-reference the cookie-jar test from the QUrl test, too.
