(GUI) VM template update does not modify IMAGE_ID

[sk4zuzu]

Description
When a VM template contains DISK = [ IMAGE_ID="2" ] and update is performed in FireEdge, then IMAGE_ID is never updated, instead FireEdge just adds IMAGE. All this makes the VM template unusable.

To Reproduce

1. Download some VM template + image from marketplace (in GUI).
2. Update the VM template and attach different image as the disk (in GUI).

Expected behavior
Either IMAGE_ID or IMAGE should exist (only one of them) and point to new image or both should be pointing to the new image correctly. 🤗
