This is all normal and is not your problem.
1) temporary file is created earlier in the process and changes are 
applied to this file.
2) original file is deleted - first unlink seen in log snippet.
3) temporary file is renamed to original filename ie the rename is from 
IMG_5858.JPG7593 not to.

The 2nd unlink (of the temporary filename) fails due to the rename 
having succeeded (=0) so at the end of that log snippet, IMG_5858.JPG 
exists and has the changed data in it.

This is the standard way you update a file safely - copy to temp file 
and make changes to it, delete old file, rename temp to original. None 
of these operations should result in data loss even if the machine loses 
power in the middle of an operation.
