AbstractQueryImpl accepts IEnumerables in SetParameterList but breaks if they're not ICollections

Commit a0e99941fe582467563ff6118b555d4ac2e55e2f changed the signatures of the two IQuery.SetParameterList methods, and correspondingly changed the signatures of AbstractQueryImpl.SetParameterList to allow passing an IEnumerable.

However, it didn't change the code which uses that value. The first line of AbstractQueryImpl.ExpandParameterList (line 240 in the current trunk) is

var vals = (ICollection)typedList.Value;

This cast fails if the IEnumerable passed in wasn't an ICollection - e.g. if it was created by a Linq Select<T, U>(Func<T, U>).
