MDL-27521 Updates the can_finalize and can_unfinalize methods to deal with passing a submission object that isn't one (in this case is a Boolean value). This will result in both methods now returning false. Kick on effect is that it corrects the bug described in MDL-27521 by removing the button if it isn't possible to finalize the submission.
