This is to allow network to watch for ANQP activity in order to fix the race condition between scanning finishing and ANQP finishing. Without this it is possible for a DBus Connect() to come in before ANQP has completed and causing the network to return NotConfigured, when its actually in the process of obtaining all the network info. The watch was made globally in station due to network not having a station object until each individual network is created. Adding a watch during network creation would result in many watchers as well as a lot of removal/addition as networks are found and lost.
