Issue with regex when test file contains mix of single and double quotes.

[benwah]

Example, if your test file looks like this:

test '#method says hi' do
  # ..
end

test "#other_method says bye" do
  #..
end

... And your cursor is positioned in the second test (#other_method says bye), C-c , s will run the test above rather, because it matches the 1st regex in the list.
