imagepruning: temporarily disable event handling

Underlying gonum/graph assigns conflicting IDs to new nodes after node
deletion. Thus two different nodes amy be assigned the same ID. This
leads to panic when an edge is set between them.

Temporarily disabling event handling until the package is fixed. This
ensures that no new nodes will be added to the graph after the first
node gets removed.
