Form build information on the session may be overridden by opening another form of the same ID

While using Rules Forms on a specific site I support, I noticed that certain actions were being fired when they weren't supposed to.

Debugging using Drupal Revisions and Rules debugger, I came through the following scenario:

1- Open a form active on Rules Forms
2- Change whichever fields needed
3- Open another form that contain the same ID (may be another content of the same type, for example)
4- The $_SESSION['rules_forms_form_values'][$form_id] will be overridden by the values of the second form
5- Submit the first form. Notice that any conditions that any condition that check the previous values is now comparing with the values for the second form instead.

The cause of this is that even if for different content, all forms of the same content type have the same ID, so the session only stores the values for one form at a time.
