b-fom-checkbox chenge event fires before update v-model

[fifzteen]

On document of b-form-checkbox, the difference of "input" and "change" is just fires due to user interaction or not.
but 'input' event fires after updated v-model value and 'change' event fires before updating v-model.
I hope 'input' and 'change' events fires same timing. after updated v-model.

Sample is here.
