[grilo-plugins/wip/carlosg/tracker3: 13/37] tracker3: Drop cursor argument from GrlTrackerOp

[Carlos Garnacho <carlosg src gnome org>]

commit 9aee2c62278d668c2fff211400f5dc98612e652a
Author: Carlos Garnacho <carlosg gnome org>

    tracker3: Drop cursor argument from GrlTrackerOp
    
    The operation is passed as data to the cursor asynchronous method,
    so it's already implicitly attached to it.
