Forces assistant to recompute the buttons state.
GTK+ automatically takes care of this in most situations,
e.g. when the user goes to a different page, or when the
visibility or completeness of a page changes.
One situation where it can be necessary to call this
function is when changing a value on the current page
affects the future page flow of the assistant.
Since 2.10
