Remove a signal to update view in KisResourceItemChooser
Before this commit, KisResourceTaggingManager would emit
a signal updateView that KisResourceItemChooser would use to call
KisResourceItemChooser::updateView().
Because views are now based on models that are syncing automatically,
updateView is unnecessary in situations that KisResourceTaggingManager
is responsible for.
This commit removes this signal and other related functions.
