Could you talk me through why your adding the is_available function? Is it not possible to update the is_installed field when Apprise is not installed?

Reworking to simply check on startup as discussed in the PR meeting.

Sticking with a mocked Apprise for the tests to stay within the scope of this issue, but for the future the tests should be reworked and expanded to use the real Apprise library for maximum coverage.
