#50 Action Pin without type leads to exception

[Jesko G. Lamm]

Steps to reproduce:

Open the HearingSystem.mdzip example model.
Delete one of the use case activities and the corresponding call begavior action (e.g. "Judge Volume")
Recreate the deleted activity and drag&drop it to the former location of the deleted action on the activity diagram.
Remodel pins and object flows, but this time without a type of the pin.

Create functional blocks and functional interfaces.

Expected: The plugin displays a warning message about the missing type (e.g. in the log window) and then ignores the existence of the pin and the corresponding activity parameter.

Observed: The plugin throws an exception.
