Fixed 1.3 regression in new "ambiguous FROMs" query logic introduced in :ref:`change_4365` where a :class:`.Query` that explicitly places an entity in the FROM clause with :meth:`.Query.select_from` and also joins to it using :meth:`.Query.join` would later cause an "ambiguous FROM" error if that entity were used in additional joins, as the entity appears twice in the "from" list of the :class:`.Query`. The fix resolves this ambiguity by folding the standalone entity into the join that it's already a part of in the same way that ultimately happens when the SELECT statement is rendered. Fixes: #4584 Change-Id: Ic62ca09c6d329695b21ed4f1be8621edcbb18e19
