Trying to fix the failing JRuby builds on Travis

The Travis builds for JRuby have been failing for a while because a scenario tagged @wip-jruby fails there. To me it seems like the options "--tags ~@wip-jruby" should be used for the JRuby build. Therefore that option need to be added to std_opts in cucumber.yml on JRuby.
The wip_opts for JRuby in cucumber.yml looks broken ",@wip-jruby" cannot be added to a string ending with "-r features". It first caught my eye in cucumber.yml, therefore I fixed that first (thinking that it should fix the JRuby build).
