Job Streams view should not consider to delete events from expressions when using drag & drop

Current Situation

• The Job Streams view considers the list of events to be deleted from an Out Condition when drag & drop for a job is used.

How to reproduce

• Create a Job Stream with three jobs.
• Job1 has an Out Condition to create an event "job1".
• Job2 has an In Condition for event "job1" and an Out Condition to create an event "job2" and to delete an event "job1"
• Drag & drop Job3 on Job2.
• This will consider event "job1" to be deleted as specified with the expression.

Desired Behavior

• When drag & drop is used the job should not consider the list of events to be deleted in the Job Stream.
