Settings: About: Fix restart and powerwash button visibility

Currently if |currentChannel_| changes after |targetChannel_|
computeShowRelaunchAndPowerwash_() will not get called and the
button visibility may be incorrect. Instead of fixing the
computeShowRelaunchAndPowerwash_() params, update visibity for
both in updateShowRelaunch_() so that they stay in sync.
