The proper signature of the function should return an RTCError,
but due to all the classes in external projects implementing it with
this signature, we need a many steps process to update this.
- Add an implementation for the pure virtual method
- Update projects not to override it
- Update the function signature
- Update projects to override it with the right signature
- Remove the dummy implementation from the interface
