Subject: MiniTest::Unit.options has default :seed

MiniTest::Unit (superclass of Test::Unit::Runner) does not has
default seed parameter, but assigned after initializing.
However some tests use MiniTest::Unit without setup of seed option
and it cases unexpected test failures. To solve this issue, add
default seed parameter 42.
