Upload storage manager improvements

[alperozturk96]

Changes

• Converts java to Kotlin
• Simplify logics

Side notes

To achieve better performance and a smoother user experience in the upload list this conversion is one of the steps.

The next step will be introducing DAO functions to get rid of cursor overhead and better thread managements from UploadListActivity and UploadListAdapter.
