bccu#1910 - better handling of not supported animation nodes.

Earlier, when a not supported animation node was hit all effects in
the same slide was ignored since the whole animation tree was
invalidated. This patch tries to minimize the impact of this issue by
removing only all children nodes of the direct parent container of the
not supported animation node.
