[Payments] If the dialog is gone, bail out

There's a poor interaction here where the Payment Request UI
goes away but the Autofill CardUnmaskBridge UI doesn't, resulting
in the UI being gone after the user inputs something into the other
dialog.

sebsg@: Rouslan's out, but this seems to be a valid way to deal with this (the
