PY-27266 Don't use ALIGN_MULTILINE_PARENTHESIZED_EXPRESSION in Python formatter

It is not actually exposed anywhere in Python code style settings and
defaults to false thus affecting parenthesized multiline (chained)
qualified references and calls. Previously, oddly enough, this
behavior was controlled by ALIGN_COLLECTIONS_AND_COMPREHENSIONS flag.
