Always send Banner patterns to the client (#11506)

Browse source 
The mojang client will not remove patterns from a Banner when none
are sent inside of an update packet, given that this is not an expected
flow for them, this is not all too surprising. So, we shall resort to always
sending the patterns over the network for update packets.

Fixes: #11487
