Add sorting to alerts list and clean up error reporting

PR#135

This release adds sorting of the alerts attributes by Alert ID. Without sorting this was causing some issues if users triggered automations by referencing the attributes instead of just the entity state. This shouldn't affect anyone's automations if you don't ever reference the attributes directly in the trigger.

PR#138 (also closes PR#140)

Cleaned up error reporting in the logs if the integration can't retrieve the alerts update.
