Move setting of the new_partition object file system usage to after
everything else, specifically after free_space_before and strict_start.
This is because snap_to_*() use free_space_before and strict_start and
snap_to_alignment() is going to be called before the file system usage
is updated to avoid the error in this bug report.

Closes #48 - Error when moving locked LUKS-encrypted partition
