container: Let subclass know adding child was interrupted

Browse source 
When the `child-added` signal emission was called, the
`GESContainer->child_added` vmethod was called (the signal is
`G_SIGNAL_RUN_FIRST`) so we need to call `GESContainer->child_removed`
ourself so subclasses know they do not control the child anymore.
