[ezaquarii]

Removing DI from the service fixes DI crash on older
devices when JobService is not provided by the system,
prevending ClassNotFoundException.

A proper fix for this issue must follow.

@tobiasKaminsky @AndyScherzinger This should fix 3.7.0 RC3.

/backport to stable-3.7

I needed to remove those two classes in question also from DI.
I tested it with Android 4.1 and 9.0 and both upload and document storage (last one only on 9.0) are working

@tobiasKaminsky needs a manual backport, unfortunately I am already afk.
