fix bad relation in Example::Schema::Result::Person
silence postgres test babble, set min_messages to WARNING
fix bad invocation of find_next_unused_port
fix ResultSet to take [] or {} as second argument

 * from https://rt.cpan.org/Public/Bug/Display.html?id=75247:
   * ResultSet is documented as having a signature of:

       $source, \%search, \%condition

     but its actual signature is:

       $source, [\%search, \%condition]

     The code seems to intend to support both, so this patch adds code
     support for the first sig, and document support for the second.
     Tests are added to 06-basic-test-schema.t for both.
docfix: Pg and replication traits already exist!
