Mike Bayer 192d3ecfdc Warn on merge of already-pending object ...

A warning is now emitted for the case where a transient object is being
merged into the session with :meth:`.Session.merge` when that object is
already transient in the :class:`.Session`.   This warns for the case where
the object would normally be double-inserted.

Fixes: #4647
