Cannot change metadata date on one photo file

[brianjmurrell]

Describe the bug

I have successfully changed the date in the metadata of many photos on my NC installation with Memories. There is one photo that the date simply always changes to the current date/time no matter what I put into the date change dialog. To be clear, Memories allows me to enter a new date but once I submit the change it just changes the date to today's date/time.

The file is named gplus-1233776374.jpg however the file utility on Linux reports that it's a PNG:

# file /var/lib/nextcloud/data/brian/files/Phone/DCIM/Camera/gplus-1233776374.jpg                                                                                    /var/lib/nextcloud/data/brian/files/Phone/DCIM/Camera/gplus-1233776374.jpg: PNG image data, 1440 x 2560, 8-bit/color RGB, non-interlaced

I have tried updating the timestamp on the filesystem with touch:

# touch -d 2016-01-23\ 19:45:00 /var/lib/nextcloud/data/brian/files/Phone/DCIM/Camera/gplus-1233776374.jpg

however Memories still shows the date it was imported as it's metadata date. But the file itself has a much older date after the above touch:

# stat /var/lib/nextcloud/data/brian/files/Phone/DCIM/Camera/gplus-1233776374.jpg

not that I think needing to use touch should be necessary (editing in Memories should be sufficient), but I just did that as a debugging step.

This issue seems similar to #921 however there doesn't seem to be any EXIF data in it to be corrupt:

PNG's exif support is iffy at best, I'll suggest just converting to another format if this is a photo. Memories uses the exiftool output, which seems to point to today's date.
