Prevent NPE when placing fading elements
This CL fixes an NPE that can happen since http://ag/27685078: the
placeWithLayer block can still run even if an element is removed from
composition.
Bug: 290930950
Test: Manual. Unfortunately it's impossible to add tests for this
because the timings solely depend on the invalidation of the graphics
layer by the Compose runtime. I have not observed the NPE with this
change, but I also didn't have manual reproduction steps.
