fix(select): Add exception for unsupported ngOptions use case

ngOptions introduced `track by` in c32a859bdb93699cc080f9affed4bcff63005a64.
Using `track by` puts constraints on the value you can use in the interpolation
expression in ngOptions. This patch adds an exception
if you use ngOptions in an unsupported way.
