First load of Quepid site, can't export a Case

[epugh]

Describe the bug
The very first page in Quepid with a case, if you go to export the case, then we see errors at https://github.com/o19s/quepid/blob/master/app/assets/javascripts/components/export_entire_case/export_entire_case_controller.js#L39

I believe that this method isn't being called: https://github.com/o19s/quepid/blob/master/app/assets/javascripts/components/export_entire_case/export_entire_case_controller.js#L26

To Reproduce
Steps to reproduce the behavior:

1. Go to http://www.quepid.com
2. Log in and end up on the Case page.
3. Click Export Case and pick General.
4. You will see it doesn't happy, and you get an undefined error in the Console.

However, if you go to the Case Drop down and pick your default case, then you can click the Export Case option.
Expected behavior
Click Export Case, and get an export.

Fixed in release 6.0.1
