HMI aborts AlertManeuver, PerformInteraction requests with STATIC images

[GetmanetsIrina]

Precondition:

1. SDL and HMI are started
2. Mobile app is registered and activated
3. CreateInteractionChoiceSet is added with STATIC image as precondition for PerformInteraction

Reproduction Steps:

1. Request AlertManeuver/PerformInteraction RPC with STATIC image

Expected behavior:

1. HMI processes the request but no not show the icon
2. HMI responds with UNSUPPORTED_RESOURCE resultCode + the message of the kind Image of '%' type is not supported on HMI. Request was not displayed
3. SDL responds with UNSUPPORTED_RESOURCE resultCode and success=true to mobile app (also with choiceId in case of PerformInteraction request)

Observed behavior:

1. HMI does not process the request
2. HMI responds with WARNINGS resultCode to AlertManeuver and UNSUPPORTED_RESOURCE resultCode to PerformInteraction + the message of the kind Image of '%' type is not supported on HMI. Request was not processed

@theresalech Please note, this is a regression issue found by Luxoft during 7.0 release manual testing.

@GetmanetsIrina please advise when Luxoft has a PR submitted to resolve the issue. However, as we are planning to release SDL 5.4 on November 5, 2020, we cannot guarantee that this PR will be included in the release.

@theresalech please notice PR with fix has been submitted and ready for Livio review

Fixed with #450 (although Core behavior does not exactly match the description because of smartdevicelink/sdl_core#1596)
