Reset typeface when changing from visible password inputType

Before, when changing a TextView from TYPE_TEXT_VARIATION_VISIBLE_PASSWORD
to a non-password input type, the typeface remained monospaced.

Fixes http://b/issue?id=2126708
"TextView does not restore typeface when changing inputType
from password to text"
