Add trailing comma via suffixLast when addCommaAfterEachArgument is false

When addCommaAfterEachArgument is false, dumpCall previously added no
commas at all. PHP CS Fixer expects a trailing comma on the last
argument in multiline function calls. Use suffixLast to add a comma
only to the last argument line instead of every line.
