Remove unused Ansible Repository page refresh

[Glutexo]

The refresh page button is no longer present on Ansible Repository Playbooks subpage. Because of that it is no longer necessary to handle pressing this button on this subpage. Remove this handling and related spec examples.

Steps to reproduce:

1. Open an Ansible Repository show page.
2. Press the leftmost Refresh button.

Now,

manageiq-ui-classic/app/controllers/ansible_repository_controller.rb

Line 43 in 2985663

params[:display] = @display if @display

is executed, even though this is no longer necessary. This line was useful only for refreshing the Playbooks subpage.

Fixes #4160. Helps #3762.

It looks good, but I need to test it. I will let you know asap. Anyway, I would add this #2419 here just for info/explanation how params[:display] = @display if @display was added there some time ago. The problem there was that wrong toolbar was chosen while displaying nested list of playbooks - and this is why Refresh button was there (but did not work well, of course, and so there was effort to fix it - to make the button work).

So it looks ok to me and it works. @skateman could you check the changes for the tests, please? :) Thank you!

Test changes are just deletions, seems okay, but travis is failing 😞

[Glutexo]

The failures and errors are from different specs and are unrelated. I can try rebasing if it helps.

Checked commit Glutexo@fafd853 with ruby 2.3.3, rubocop 0.52.1, haml-lint 0.20.0, and yamllint 1.10.0
2 files checked, 0 offenses detected
Everything looks fine. ⭐

I believe that at least here I am innocent. Travis is failing because of yarn timeout.

[skateman]

@Glutexo probably yes, I will try something 😉

Just wondering, if the [technical-debt] flag means that the PR reduces the debt or increases it. 😅

@Glutexo It means it reduces the tech. debt.
