Fix NPE from flagTransform

The bug affected loading of route graph connections about to be split in
half when attached to diagram flags at either or both ends.

The NPE caused the flag terminal position to receive identity transform
as value which is plain wrong. This in turn resulted in the splitting
position being completely wrong compared to what the user requested and
the result looking very strange.

This fixes the immediate problem but still doesn't work properly if the
flag is actually attached to a diagram template flag table. In this case
the terminal's position will be incorrectly calculated since
runtimeDiagram is null. This needs another issue.
