If a user uses the back button to get back into an AW form to edit, cancel checkout fails

A couple of things with the fix for #1021:

issue
After using the back button to get into an AW form, if you try to cancel the checkout (exit without saving), an error is thrown:

2016-03-03 13:36:58,752 48296744    TP-Processor8   ERROR   RESTService required condition condition-lockedbyme   failed, cannot execute action
com.tsgrp.opencontent.core.exception.OCRuntimeException: required condition condition-lockedbyme   failed, cannot execute action
    at com.tsgrp.opencontent.core.action.executer.AbstractActionExecuter.execute(AbstractActionExecuter.java:179)
    at com.tsgrp.opencontent.core.action.service.CoreActionService.execute(CoreActionService.java:321)

It looks like the code that fixed #1021 simply sends the user to the newest version of the form - it doesn't actually check it out again.

Enhancement
While fixing this, can we give the use a "no" option when using the back button? Our solution to #1021 fixes the issue, but also basically forces the user to edit the form. We should give the user the option to not edit the form.

so if the user selects OK we need to make sure the checkout happens when visiting a /edit/ route and then add a cancel button that hits the /exit route.

yep - probably hook up the [X] in the top right to do the same thing as the [Cancel] button. Right now, no matter what you do, it takes the user into editing the current form (without checking it out)
