Fix false positive in Layout/DotPosition

This fixes a false positive in Layout/DotPosition where an offense would
be registered for the trailing style when the receiver was a method call
with multiline arguments, and the selector was on the same line as the
receiver's closing bracket.

For example, before this change, the following offense would be registered:

    foo(
      bar
    ).baz
     ^ Place the . on the previous line, together with the method call receiver.
