Submitting the "Edit Residency" form throws a server error:

Error: Move out is not a valid date in residencies insert

[brylie]

Please make sure dates are valid in all form submissions for:

• Add residency
  • new resident
  • existing resident
• Edit residency

Try with combinations of

• both "move in" and "move out" dates
• just "move in" date

All form fields should submit valid dates to the server.

@brylie the form titles were incorrectly shown. Also, fixed the date issue.
