HMI does not take app priority into account for Alerts

[jacobkeeler]

Bug Report

If two apps attempt to present an Alert at the same time, the HMI will try to present both Alerts. The HMI should only present the Alert from the app with a higher priority value.

Reproduction Steps

1. Register two apps with permissions for the Notifications group. App 1 with "priority": "NORMAL" and App 2 with "priority": "NAVIGATION"
2. Activate App 1
3. Activate App 2
4. Send Alert from App 1
5. Send Alert from App 2 while the first alert is being displayed

Expected Behavior

Original Alert should close and App 1 should get an ABORTED response

Observed Behavior

Both Alerts are displayed on top of each other, and both apps receive SUCCESS when these Alerts are closed
