privacy: Actually set the blacklist preference

The preference was not being set, which caused this code to throw an NPE on
devices without telephony when opening the privacy preferences.

This bug also affects devices with telephony in that the preference doesn't
update its text. I also got rid of the null check because the preference
always exists, the null check is pointless and ended up hiding this bug.

Settings: add a way to open blacklist settings externally

Opening the activity doesn't theme the switch bar - an alias works.

blacklist: make it possible to unblacklist phone/messages via checkboxes

Change-Id: I7d982d17818efe065e4e22f2a86a46493672584a

Settings: fix blacklist settings crash

On a device rotate, the MultiSelectListPreference would try and restore
its state since the preferences aren't persisted. Clear the persisted
flag so the MultiSelectPreference doesn't try and restore the states, as
they get populated in onResume().
