Stop linkifying addresses.

Address linkification on Android is pretty busted, and the docs
acknowledge it (see Linkify#MAP_ADDRESSES). Safest thing to do
at the moment is remove it. Looks like we may be able to get
better address linkification on API >= 28, but adding it will
be more involved.

Fixes #7730
