Revert "Add wait for location import task"

This reverts commit dca4bc830e016981fd5d15b7097b8f8b4899e935.

Reason for revert: We wait for the hash calcuation to finish
in the test which is fixed by [1] so we can remove the wait
part and proceed with image deletion when the location add
task ongoing.
