Fix capybara deprecation of passing an int
What does this MR do and why?
Fixes a deprecation warning that occurs when a integer is passed to a capybara link in the pipelines feature spec.
Warning is:
Locator Integer:1 for selector :link must be an instance of String or Symbol. This will raise an error in a future version of Capybara.
How to validate
Run the spec/features/projects/pipelines/pipelines_spec.rb
and see the deprecations.
Run the spec with the new branch checked out and see no deprecations.
