Improve retry failed uploads function

[JonasMayerDev]

trafficstars

Simple optimization to the retry Uploads function. The main improvement is to not restart the worker for every upload, but just update the database and in the end restart the upload worker for each account once.

Should solve some inconsistencies in the upload tab when handling a lot of files (around 7000).
