Enable Ethernet tab in data usage

mStateSession is not initialized at the time hasEthernet is called to
set mShowEthernet, so Ethernet tab is not shown at the startup.
In this case, if the device doesn't support mobile network, user cannot
even select it from the context menu.

Settings : Fix accessibility shortcut

Shortcuts like accessibility, have preferences with titleText rather than
titleRes as their title. Settings only had a override for titleText, which caused
preference screens inside accessibility to not work. This commit addresses that.

Reproducable via :

1. Create a settings accessibility shortcut.
2. Launch shortcut and try to open an of the services

Expected behaviour : Appropriate ToggleAccessibilityServicePreferenceFragment should open
Observed behaviour : Same Settings instead gets relaunched instead

Correctly remember MAP access selection.

Previously, the MAP access notification used to pop up on every BT
connection. 'Don't ask this again' didn't work. Fix that by correctly
remembering not only the PBAP access selection, but also the MAP access
selection.
