Allow test to be an unparenthesized method

[reese]

Closes #383

test works just like it and describe in Rails tests, so I think it's fine to let it not use parens just like the other test methods.

what if we just did a sin and forced all these methods to be parenthesized?

Would love to see it get merged.

@fables-tales Rails and a bunch of ruby test frameworks use these without () today. It makes it readable, plus that is the accepted norm. Sometimes the rails test runner doesn't pickup the line-numbering when defined with test("my test case") do; end when running a single test case.

Could we add context to this list as well? It's so weird seeing rubyfmt adding braces to all my context 'xxx' do methods, while leaving it and describe without them.

And similarly all other RSpec "helper" methods should also be left without parenthesis: to, not_to, to_not, be, eql, include and so on.

Observing expect(country).to eql 'Ukraine' be transformed into expect(country).to(eql('Ukraine')) is just not great as the existing convention, which I believe to be the norm, is to omit parentheses in such situations.

I wish this was configurable in some way for the end user, though I understand the goal of the project being configuration-less.
