Add failing tests for Simple console route

Hi,

This PR adds a few tests for route that should work according to the doc but does not. Unfortunately, I've been unable to fix the SimpleRoute (which is everything excepting simple to understand), as my regex skills are far below average.

ping @weierophinney, @ralphschindler

(the ones that fails are: literal-optional-long-flag, literal-optional-long-value-flag and combined-1).
