Fix issue with bindings to aliases that cannot yet be resolved
When an alias points to a child object which has not yet been
initialized, it's id won't have been registered yet, so setting up a
binding to it will result in a crash.
The fix is: when setting a binding target fails, and its target property
is an alias, queue them until all bindings have been set up, and try
again.
