with missing RECURSIVE

If a table reference r used inthe specification of a CTE whose definition
is contained in the WITH clause where RECURSIVE is omitted then this table
reference cannot be considered as a recursive table reference even if it is
used in the query that specifies CTE whose name is r. It can be considered
only as a reference to an embedding CTE or to a temporary table or to
a base table/view. If there is no such object with name r then an error
message must be reported.
This patch fixes the code that actually in some cases resolved r as a
reference to the CTE whose specification contained r if its name was r
in spite of the fact that r was not considered as a recursive CTE.
This happened in the cases when the definition of r was used in the
specification of another CTE. Such wrong name resolution for r led to an
infinite recursive invocations of the parser that ultimately crashed the
server.
This bug is a result of the fix for mdev-13780 that was not quite correct.
