select model not reset if valid options changed by ng-options

[clkao]

If a select's options (from ng-options) are changed, and the current value is no longer in the list, the model value should probably be cleared.

tested on chrome and 1.2.13.

Thanks @clkao ! Looks like a valuable item to investigate and / or resolve.

@IgorMinar @btford @caitp looks worthwhile looking into in the near future.

PRs welcome, IMO. This seems like it should be relatively easy to fix --- although, fixing this is possibly a breaking change.

thanks @caitp that does make a lot of sense!
