Reformat underscore-style test names

Ruby tests are written like this:

def test_can_open_metadata
  # Test
end

When the Test::Unit tests are run through CI Reporter and played on Bamboo, they show up like test_can_open_metadata. A Java test named testCanOpenMetadata() would show up as _Can Open Metadata, which is nice from a legibility perspective. Would be nice if Bamboo could do the same with ruby test methods, so t hat it would show up as Can Open Metadata as well.

This is just one more way that Bamboo could enhance its support for Ruby on Rails development.
