The `RAILS5=1 rspec spec/controllers/admin/application_settings_controller_spec.rb`
command throws the error:

Failures:

  1) Admin::ApplicationSettingsController PUT #update falls back to defaults when settings are omitted
      Failure/Error: import_sources = params[:application_setting][:import_sources]

      NoMethodError:
        undefined method `[]' for nil:NilClass
      # ./app/controllers/admin/application_settings_controller.rb:62:in `application_setting_params'

This commit fixes it.

[Rails5] Fix running spinach tests

See merge request gitlab-org/gitlab-ce!18281

Previously whenever you'd schedule a chatops command we'd respond with
the message "The command has been scheduled!" which was a link to the
new build. Such messages can get annoying very quickly.

Fortunately there's a trick we can use: when you send back an empty
message Slack won't show said message, but it _will_ show the input
command.

Reduce complexity of issuable finder query.

Closes #37125
