CallStyle: don't reglue icon+label if never glued
EmphasizedNotificationButton has two ways of rendering the icon and
label:
1. Unglued, where they're set using View's standard methods.
2. Glued, where they're saved and combined into a single Spannable with
an ImageSpan for the icon.
A small logic error meant that we were "re-gluing" the icon and label on
layout direction updates *even if they weren't glued to start with*, and
gluing a null icon and label gives a blank button instead of the label
the caller already set.
