Fix 500 when saving /site/edit without email When saving /site/edit with no no_reply_email set, a 500 error page would be returned due to an empty value being passed as value to the datastore (which is not allowed for email fields).

"""
 This module houses the OGR & SRS Exception objects, and the
 check_err() routine which checks the status code returned by
 OGR methods.

    This exception is raised when an invalid index is encountered, and has
    the 'silent_variable_feature' attribute set to true.  This ensures that
    django's templates proceed to use the next lookup type gracefully when
    an Exception is raised.  Fixes ticket #4740.
