Added a Then step for iOS template tests

Also slightly refactored the Then step for OS X. This could be made
much more DRY, and the Then regex could actually take into account
that the project dir is not always 'template-project' and the spec
target is not always 'Specs'
Add failing 'spec suite' and 'spec bundle' tests for iOS rake templates

- Update cucumber tests to cover these scenarios
