closure: fix a bug in goog.fx.dom.bgColorFadeIn where computedBgColor was
sometimes being computed as empty-string, which goog.color.parse fails to parse.
It's possible this is just masking a bug in goog.style.getBackgroundColor, but
this is a good fix regardless since the code already defaults to white when it doesn't
know what else to do.
