Stop Predecessors from being deleted when a date is deleted

mtp105

Sometimes we need to just delete the dates to start fresh or copy rows to use for another project, but deleting the dates also deletes the predecessors. I was trying to test a schedule template with many hours of work on defining the predecessors. When I wanted to blank out the dates again so it could be used as a blank new template, all the predecessors were also deleted. This can also happen accidentally when users edit a date, which then deletes the predecessors without them realizing it. So if the date shifts again but is still dependent on a previous task, that relationship is lost.

Please change this functionality of predecessors being deleted for ANY reason, unless the user deliberately deletes a predecessor directly.
