Steps to reproduce:

1. create a new process similar to the attached screenshot of a process
2. start a new instance of this process
3. correlate a message to the non interrupting boundary message event (the userTask after the boundary event is now active)
4. correlate a message to the receive task

-> the userTask (after the boundary event) has been canceled

Problem:
After the correlation of the message to the non interrupting boundary message event the execution tree looks as follows:

PI <--- e1(SubProcess) <-- e2(ReceiveTask)
\
e3(UserTask)

But the execution tree should look like this

PI <--- e1(SubProcess) <-- e2(ReceiveTask)
\
e3(UserTask)
