Log Message:
-----------
== Sequencer ==

This fixes: [#11642] VSE: crash with Speed Control and play head

Special sequence update (holding down left mouse button on a strip)
could lead to a crash when using the speed control effect, since
we didn't check properly for valid cfras (and therefore if
TStripElem is null... )
