Test against the real value of tld_length unless explicitly set

There were two places where the tld_length default
was hard-coded to 1, both overriding the real default
value of ActionDispatch::Http::URL.tld_length in this
set of tests.

This commit removes both of those, relying on the
actual value of ActionDispatch::Http::URL.tld_length,
unless it's specifically overridden.
