Handle port numbers in default token_audience

This MR handles setting the default token_audience when the server is included with a port suffix. The fix is to look for tokens with audiences that both include and exclude the :port suffix.

requested review from @duncan.meacher

@duncan.meacher, this fixes a problem where querying https://datafind-dev.ligo.uwm.edu:443 would look for a token with that exact audience (including the :443 port suffx), which isn't what we want.
