Toolbars on open chat dialog have to be updated automatically on plugins enable/disable

[Ri0n]

The current version instead making action visible/invisible instead deletes or add them. For toolbar this action deletion is somewhat unexpected so the icons stay on the toolbar usually leading to a crash on an attempt to use them.

The toolbar icons are copies of the original icons in the actionlist. So basically on making a copy we need to connect a signal like if original is removed the copy has to be removed as well.

if original is removed the copy has to be removed as well

Do not forget about adding of actions to toolbars after enabling of plugin please.
