Issues

Now that fetching users is being paginated

• fix: paginating fetch multiple users request [WPB-4999] #2158

Users in huge teams (1000+ users) can properly fetch all contacts during slow sync. But #2158 doesn't trigger slow sync again.

Solutions

Bump the SlowSync Version, so Kalium will trigger it again after updating the app.

Also, move it to be private inside the class, as there's no reason to make it publicly available like it was before.
