[BUGFIX] Processed files get corrupted when regenerated

After a file is being (re)processed, the information about it is updated
in the database by the ProcessedFileRepository. The repository gathers
information for the update from the processed file.

For unprocessed files (i.e. those where the original file should be
used), the ProcessedFile class does a fallback to the original file
object. Unfortunately, this fallback is also applied for the uid
property, which makes the repository overwrite a random record in
sys_file_processedfile. This leads to wrong images being displayed in
the frontend.

This patch makes the processed file only return its own uid.

IMPORTANT: To make sure your sys_file_processedfile data is not
corrupted, empty the table and your processed files folder (usually
fileadmin/_processed_/). This will slow down your site as all processed
files are regenerated, but afterwards all data will be correct.
