Bug description

When the nextcloud client encounters an error (red exclamation mark in the taskbar), the sync process does not resume. This can only be done by clickin on the "Sync now" button besides the "Some files could not be synced" message.

Steps to reproduce

Difficult to reproduce as it needs an error condition

Expected behavior

The client should always try to resume the sync process. Specially for fresh installations the initial sync process should be able to run unattended and without an need for manual intervention. The only error exception are authentication errors because these usually do not resolve automatically.
