Reword recent error messages: "should" -> "must"

Browse Source 
Most were introduced in the 17 timeframe.  The ones in wparser_def.c are
very old.

I also changed "JSON path expression for column \"%s\" should return
single item without wrapper" to "JSON path expression for column \"%s\"
must return single item when no wrapper is requested" to avoid
ambiguity.

Backpatch to 17.
