Use base.create_flavor in servers test

This is to replace the multi-lines of creating flavor with
one call to base.create_flavor, so the code will look simpler.

Besides, _get_unused_flavor_id in ServersAdminNegativeTestJSON is not
necessary, for the random flavor id can hardly duplicate with the
existing ones.
