Do not perform SDP during pairing

Do not perform SDP during pairing

As a result of commit 7de119c (ag/591931), SDP is performed when the
pairing dialog pops up. There are multiple problems with this. On badly
behaved devices an SDP request might trigger pairing from the remote
side, other devices (like Logitech keyboards) will close the connection
once SDP disconnects, causing the pairing to fail.

Further more, fetchUuidsWithSdk() is an asynchronous call. The code that
was added does not wait for SDP to complete. Thus the check for the PBAP
UUID will always fail and cause the permission check to still be
displayed.

With this change, SDP is not performed when the dialog is popped up and
PBAP permission is granted after bonding and subsequent service
discovery in accordance with final consensus in bug 16964116.
