Remove all occurences of endDate

[bledsoef]

Issue Description

Fixes issue #1348

• End date is current a field in our database for events but it is never needed nor necessary. Remove it from the database and wherever else it appears.

Changes

• Deleted endDate from the event model
• Deleted all unnecessary references to endDate in the tests.
• It should be noted that endDate is still necessary in some instances for event preprocessing for recurring events, but it should never make it to the database.

Testing

• Checkout 1348_remove_end_data
• Source setup
• Reset database
• Run tests
• Go through event functionality like creating recurring and non recurring events, viewing events, etc. and verify nothing is breaking or working incorrectly.
• Look through code and tests.

Remove all occurrences of endDate

[stevensonmichel]

I created a recurring on December 3rd, with the end date being December 23th. It successfully generated three weekly events, which occur on 3rd, 10th, and 17th. However, on the edit page for each, their start date is marked as 23rd.

That inconsistency needs to be addressed
