TextView setText/append methods set movement method

Previously, TextView setText and append methods set the movement
method to LinkMovementMethod only when autoLink was enabled and
Linkify was able to find links in the input text. This CL adds the
case where autoLink is false, linksClickable is true, and the input
text contains ClickableSpans.
