In #14627 we added some logic that removes the selected button toggle from the selection when it's destroyed. In an attempt to work around a "changed after checked" error we wrapped the call in a Promise.resolve, however that introduced an issue where we might end up overwriting a subsequent value, if it happens immediately after a button is destroyed. These changes move some things around to ensure that we don't overwrite the user's value.

Fixes #15297.

@crisbeto this passes presubmit, just needs a rebase

… contains the selected value
