Fix crash in CachedBluetoothDevice.

In LocalBluetoothProfileManager, we will update profiles in constructor
by register service callback to bluetooth profiles. So the callback may
return before this constructor, in which case mBluetoothProfileManager
maybe null in LocalBluetoothMangaer.

This cl moves the updateLocalProfiles() out of the constructor, to make
sure we will first construct mBluetoothProfileManger and then connect to
bluetooth profiles.
