auto-t: AdHoc - address race condition

Browse Source 
The AdHoc methods used to miss the change in properties
on AdHoc interface. To address the race condition, we
subscribe 'PropertiesChanged' signal first and then do
GetAll properties call. This way we are not missing
'PropertiesChanged' signal in between these calls.
