* Ensure that the system works at startup and after Clear. Ensure the invalid entityId is not added to the list.

Signed-off-by: Danilo Aimini <82231674+AMZN-daimini@users.noreply.github.com>

* Return a const reference to the list of entities in FocusModeInterface

Signed-off-by: Danilo Aimini <82231674+AMZN-daimini@users.noreply.github.com>

* Fix SetFocusRoot to trigger notifications appropriately

Signed-off-by: Danilo Aimini <82231674+AMZN-daimini@users.noreply.github.com>

* Optimize the entity removal via swap and pop, since we don't care about the order.

Signed-off-by: Danilo Aimini <82231674+AMZN-daimini@users.noreply.github.com>

* Introduce additional check to prevent possibly adding the same entity to the list twice.

Signed-off-by: Danilo Aimini <82231674+AMZN-daimini@users.noreply.github.com>

* Fix mock after API changes

Signed-off-by: Danilo Aimini <82231674+AMZN-daimini@users.noreply.github.com>

* Typo.

Signed-off-by: Danilo Aimini <82231674+AMZN-daimini@users.noreply.github.com>

* Fixed logic that needed to be updated when the code was moved.
