Date format fix

[caleballdrin]

Description

The Graduation date question displays the entire date/timestamp from the API when looking at past registrations. When displaying the dates, format them to make them more readable.

Changes made

• Removed logic around formatting the initial date when loading a date picker. The full date/timestamp is fine. Each datepicker formats the displayed date based on what kind of question it is.
• Formatted the dates in a readable format when they are displayed throughout the ERT.
• Added new tests to check the initialDate

We need a write multiple tests and maybe multiple test pages for this change since it affects a lot of functionality.

@dr-bizz I reorganized some of the tests to make them more clear. Are these enough tests? What other things should I test?

This looks good to me. Can you push this to the stage and let me know when you have so we can test it there before it goes live?

@dr-bizz i put it on staging yesterday. So you can test whenever.
