Fixing Actors bug where if you have an empty aliaes, add two aliases, and then delete both aliases, refresh the page and the last item to be deleted will not be deleted. The database shows a list of [last_item, '']. The empty string should not be in the list. This commit fixes the empty string. This same bug might exist in other areas?
Incorrect existence check, length could be zero and you would never be able to add aliases.

convert the string value to a datetime object. This will allow you to do
accurate querying with operators such as `__gt`, `__gte`, `__lt`,
`__lte`, etc.
Don't create new identifier on attribution.

Identifier has to exist on attribution. This prevents appending
organizations to source lists that didn't provide that identifier.
