[API] Incorrect or absent File name in endpoints /projects/{project}/images and /projects/{project}/recordings

[spell00]

Describe the bug
The File's name is incorrect in endpoint /projects/{project}/images and absent in /projects/{project}/recordings.

To Reproduce

1. Go to <hostname>/api/v0.0.3/projects/pumpernickel/recordings.
   

File is actually the path. The first item of the list should have be the file's name.

2. Go to <hostname>/api/v0.0.3/projects/pumpernickel/images
   

There is no File attribute and there should be one, like for the recordings.
