Use application list to determine if team is empty

[knolleary]

Fixes #2031

Description

Uses the application list api to determine if the team is empty or not.

Adds test coverage for the team delete ui.

Note: I've had to add the new _spec file to the list of those for which the require-data-selectors lint rule is disabled. This is because the fix is needed upstream in ui-components to add data attributes to the ff-dialog components.

There are chrome plugins but they tend to be not great.
