- Fixed bug in Oracle dialect where reflection of tables and other

symbols with names quoted to force all-lower-case would not be
identified properly in reflection queries.  The :class:`.quoted_name`
construct is now applied to incoming symbol names that detect as
forced into all-lower-case within the "name normalize" process.
fixes #3548
