[BUGFIX] Don't duplicate thumbnails in file list and file selector

Default width and height for thumbnails is now applied in ProcessedFile
thus configuration column of the sys_file_processedfile table is filled
even if empty configuration was passed to File->Process().

This prevents thumbnails with the same content but different names being
generated, thus improves performance.

Resolves: #81776
Releases: master, 8.7, 7.6
