Tim Hunt 81e47a35e8 MDL-53304 question behaviour: don't show useless Check buttons
Previously, the Check button was often shown disabled when it
could not be used (e.g. when the question was finished, or when an
interactive question was in the try-again state). Eventually we
realised it was better usability to hide it in these cases.

Note that when a teacher reviews an in-progress quiz attempt, they will
see a disabled Check button if the student doing the quiz can see the
button.
