Added a step to define an issue with a list of attributes.

Example:
And there are the following issues with attributes:
      | subject     | project        | author  | watched_by |
      | Test-Issue  | tested_project | bob     | bob        |
      | NOT-WATCHED | other_project  | bob     | bob,mary   |
The feature had a wrong/ambiguous) label ("Create Project") and needs to
be disabled for the openproject_my_project_page-plugin.
