[Bug 1889640] [NEW] Image import might result 'active' image with no data.

 

Public bug reported:

There is two scenarios where Interoperable Image Import might result
'Active' image without image data in it.

1) If the data from staging was deleted by the time task tries to delete it.
    * In This scenario the taskflow will hit revert chain, delete the image from the stores it had just uploaded, but will not revert the set_image_data() changing the image to active.

2) If the 'all_stores_must_succeed' was set to 'false' and all uploads fails.
    * As we ignore the individual store failures in this scenario the taskflow will finish and when it gets to _SaveImage it will finally set the image active even we have no locations.
