core: import glance image - image locked on failure

ImportRepoImageCreateTaskHandler:
Ensure 'destinationImageId' member of 'ImagesActionsParametersBase'
is saved in task parameters as part of AddImageFromScratch
execution. This change is needed from retrieving 'destinationImageId'
value in case of engine crash between tasks.
