Fix #2422 & #2433 - make sure puppetdoc transform AST::Leaf boolean correctly

AST nodes don't have a valid to_s that is producing a correct
representation of said node.
This patch adds some of the AST node to_s to produce correct
values that can be used verbatim by puppetdoc to render
the documentation.
