Bluetooth: Set isPreferred to true for PanProfile Connections.

isPreferred is always true for PAN profile so that DUT can
initiate connection with remote device. Curretnly we are
returning true only when pan profile is in connected, so
it will return false when pan profile is not connected and
will never initiate connection on click.

Bluetooth: Remove remote device from trust list on BOND change

A special case where remote device is paired & authorized by
DUT. Remote device is unpaired by itself & try to connect again.
In this scenario Link key is deleted from remote device. So
SSP is performed again. & remote device bond state is changed
to BOND_BONDING from BOND_BONDED on DUT while SSP, As it was
in DUT BONDED list. So permission/trust info for all profile
need to be false when it's moved to BOND_BONDING to solve the
issue.
