Binding aware mount point is not available sometimes

Binding aware mount point is not available in some scenarios, where binding-aware part of controller is not fully initialized and DOM mount point is already present.

Code for binding-aware mount points relies only on asynchronous events, which means when DOM mount point is started before Binding-Aware mount point, binding-aware mount point is not available to clients.

Solution to this is: if mountpoint does not exists, II will be translated to DOM and query for mountpoint will be issued.
