Remove check for click:close listener in VChip.hasClose (#7468)
Remove check for click:close listener in VChip.hasClose (#7468)

Presence of close button shouldn't depend on presence of the listener. If I want to dynamically change visibility of a close button on v-chip I have to manually add / remove listeners. Also it isn't mentioned anywhere in the docs that just having click:close listener attached will make close button appear.
