Enable Back-key when go to Emergency call

When go to "Emergency call" from lock screen, back key is disappeared.
It is difficult for user to find the way to go back to previous screen.
This might be bad user experience. So we are going to make it enable.

Settings: recover last location state during on/off switch

based on the behaviour change on QS here:

https://gerrit.slimroms.net/#/c/1421

we go now same way in settings. Tbh not sure what the goal is to
force the user after switching off to enable always high accuracy
location. Whatever we use here same attempt like in QS tile....if the
user switches on again it recovers the last enabled state.

HTML injection fix for bluetooth pairing, issue 65946

During bluetooth pairing, HTML injection is possible via the device name displayed to the user. This escapes the device name, before creating HTML from it, so it will preserve things like < and > but will not affect rendering of HTML

Bluetooth: Don't set a null alias before unpairing

* This causes the unpair action to throw a null pointer exception and
  bring down the Settings app. Don't do this.
