Teiid connection importer looses its translator setting during "< back"

When Teiid Connection importer is used, after creating a datasource, if user selects "translator" setting, for any reason if the user uses "< back" in wizard and come back, then the translator is switched back to "jdbc-ansi", if user does not pay attention, the process fails with most data sources.

Once user selection is made, that should kept in tact until user changes it again.
