Tag support incomplete and broken

[pjlsergeant]

From a bug report by Craig Caroon:

1. Executor::execute() does not filter by tags

I discovered that, although the documentation says otherwise, the execute() method on Test::BDD::Cucumber::Executor does NOT in fact accept an optional TagSpec parameter and then filter the scenarios to be run by those tags.

1. Scenario level tags are NOT recognized for the first Scenario in a feature file UNLESS there exists a Background section.

Without the Background section, the first set of Scenario level tags are gobbled up by the code that parses off the Conditions of Satisfaction, '_extract_conditions_of_satisfaction'.
