Setting I and O in timline change layer point I/Os even when layers are locked

set a layer up, track the middle of a shot with it setting I and O in TL
lock layer - note its I and O points
with layer still selected, change TL I/O points to either start / end or anything else
note that layer has now changes its I/O points to match TL I/O even while locked. you can’t change the layers I/O points with the layer controls when locked ( correct ) but can with TL.

bit me bad yesterday… please fix so that when a layer is locked, its really locked
