unicorn still complains about -P flag, when using just "unicorn" as name

[toadle]

Hey guys,

I noticed that here https://github.com/gds-operations/unicornherder/commit/f9e016950c38f7a43b36b8d03a89b18542345433 the -P flag gets excluded for unicorn_rails to keep it from complaining about using this flag.

Now we had unicorn as name and our unicornherder command looked like this:

bundle exec unicornherder -u unicorn -t 60 -p /somepath/some.pid

in this case unicorn still complains about the -P flag cause it still gets passed on.

I don't really know about gunicorn and stuff, but I think that for just unicorn the -P flag should also be left out.
