Fix updating button options with mergeOptions (#6219)

Updating button options with mergeOptions stopped working in 6.5.0. The regression was introduced by #6090. When updating buttons, RNN didn't take button options into account when checking if two buttons are equal, instead it checked only by button id.

closes #6205
