Title: Auto connection not getting initiated after pairing

Issue:
mProfiles list getting corrupted as its not protected with
lock and auto connection failing

Steps:
1.Turn on BT
2.Scan the remote headset from DUT
3.Initiating pairing to remote device
4.unpair the remote from DUT UI

Repeat steps from 2 to 4. Some times auto connection not
getting initiated from DUT.

RootCause:
if mProfiles accessed simultaneously from onUuidChanged and
connectAllEnabledProfiles ,its leading to list corruption.
Settings not able to initiate Auto connection as mProfiles
list shown as empty.

Fix:
Remove redundant mProfiles empty check in onUuidChanged

- mProfiles accessed inside onUuidChanged without syncronization,
  if mProfiles accessed simultaneously from onUuidChanged and
  connectAllEnabledProfiles ,it might lead to list corruption.

- mProfiles empty check already there in connectAllEnabledProfiles

Hence removing  mProfiles empty conditional check in onUuidChanged

Test: Follow steps above
