Supply expected values to GetIdentitySelectString

The entity persister was supplying the table name as the column
parameter and the column name as the table parameter. This has no effect
on NHibernate tests because GetIdentitySelectString does not use its
parameters by default and no built-in dialects overrides it for using
them.

Fixes nhibernate#1635
