[Bug ] Incorrect script/container behaviour that may result in broken installation/incompatible state

[jiaz83]

Idea

Whenever JDownloader is updating itself/Core, the main process is gone, while the helper installation process is applying the updates. The script currently doesn't properly wait for this process to finish, which then may result in incomplete installation of updates. In case of no or broken JDownloader.jar file, it is getting replaced by bundeled/old JDownloader.jar

Whenever the JDownloader.jar is replaced, it is important to also delete Core.jar file and the update directory.

Please feel free to get in contact with our support for further solution finding

1.) properly wait for updater process to finish
2.) update init script to also delete Core.jar file and update directory whenever JDownloader.jar file is replaced

I may add that me and @jiaz83 are official JDownloader staff.

Thank you for your input, it's really appreciated. I think point 2) is clear, but the first one definitely requires more thoughts.
