Unable to add 2 actions of the same type to a model

Problem/Motivation

It appears to be impossible to add 2 instances of the same action to a model - for example, 1 send email action to send an email to Bert, and a second send email action to send a different email to Ernie.

If you attempt to add a second instance of the same action type, instead of a second one being created the first will be updated.

I haven't tested all available actions, but enough to suggest that it's likely to be present for all.

Steps to reproduce

1. Create a new model
2. Ad an event - for example cancellation of an account
3. Add and save an instance of the send email action
4. Attempt to add a second instance of the send email action

Rather than ending up with two instances of the send email action, the first will be updated with the data that you entered when attempting to create the second action.

Note that the status message displayed after ‘adding’ the second action does seem to indicate that the existing action has been updated rather than a new one saved.
