Fix position error in annotation parameter list parsing

Prior to this commit, an annotation with one or more parameter lists
would have incorrect positions attached to each parameter list.  For
example, the annotation

    @foo("bar")

would have the erroneous position `<4..10>` attached to its `Apply` node
instead of the correct position `<4..11>`.  This was caused by forget-
ting to take into account the closing parenthesis.
