Only 10 transfers visible / executed

Expected behaviour

A user can see all of his transfers in the app somehow. Maybe a couple (configurable amount) are shown by default, and on the bottom of the list, a "load more" button allows showing of more transfers. No matter how many transfers are displayed, all transfers are executed, e.g., even if the list is filled with failed transfers, other transfers that are not visible are still executed. (Connected to #521)

Actual behaviour

Only 10 transfers are visible. The user is not able to see more of his transfers than the first 10. When the list is filled up with failed transfers, no other transfers are executed. (Connected to #521)

Steps to reproduce

Spawn a couple (e.g. 50+) transfers, e.g. by marking a folder as a favourite and having "Favourites available offline" enabled in settings.

Reproduce the issue by creating 50+ transfers through a folder with “Favourites available offline” enabled, then inspect the transfer list and execution flow. Focus on the 10-item display limit and the interaction with failed transfers. Done means users can access all transfers, optionally load more, and every transfer executes regardless of which items are visible.
