[PATCH 6/7] t3419: drop unnecessary NOT_EXPENSIVE pseudo-prerequisite

[Junio C Hamano <gitster@pobox.com>]

This was only necessary because do_tests helper the script defines
took its parameters in a wrong order.  Just pass an empty string (or
not passing the optional EXPENSIVE prerequisite) when running the
test with a light-weight set of parameters and have the shell do the
right thing when parsing test_expect_success helper.

Also update coding style while we are at it.
