Alert and SubtleAlert Respond ABORTED on timeout

[iCollin]

Summary

If you send an Alert or SubtleAlert with soft buttons and do not interact with the HMI in any way, the HMI will reply ABORTED when the alert times out.

Reproduction

Start and connect HMI, App, Core
Send Alert or SubtleAlert with soft buttons
In case of Alert, wait for 30 seconds
In case of SubtleAlert, wait for 10 seconds

Expectation

Core receives SUCCESS response
Mobile receives SUCCESS response

Actual Result

Core receives ABORTED response
Mobile receives ABORTED response

Fix

I plan to prepare a fix for this issue after merge of 0189.

I found this behavior is correct according to the requirements, and the behavior of the Generic HMI is incorrect.

An issue has been opened to match this behavior there: smartdevicelink/generic_hmi#420
