The "Run Focused Should" commands fails when there's no enclosing context

[contentfree]

This simple case fails:

class SubscriptionTest < ActiveSupport::TestCase
  should belong_to :user
end

It results in:
-:16: undefined method `empty?' for nil:NilClass (NoMethodError) This doesn't appear to be a TestCase class.

context is nil in this case, with the current command's code. A check for nil? would fix the error however, it would then disallow running the non-enclosed shoulds.

Additionally, even if the context being nil issue was solved, no focused should would be ran since should belong_to :user doesn't have any quotation marks to match. This is likely something that can't - without a lot of work - be hacked around.

I believe I fixed this in my fork.
