Fix testing of parallel-safety of scan/join target.
In commit 960df2a971 ("Correctly assess parallel-safety of tlists when
SRFs are used."), the testing of scan/join target was done incorrectly,
which caused a plan-quality problem. Backpatch through to v11 where
the aforementioned commit went in, since this is a regression from v10.
