output-management-v1: send complete head state on enable change 

The data of a head is only sent when it is enabled. While the head was disabled
data might have been changed. In this case clients were not informed about this
change. A later enable change that does not also update the other data must
still lead to the propagation of this data.

Since we do not know what other data was changed while the head was disabled
just send together with an enable change all current data.
