Fix link additional text in doxygen

\link Abcd#setEfg() this is a link\endlink works, it provides a linkon the text "this is a link"
But if we add an an object as argument
\link Abcd#setEfg(bool) this is a link\endlink it fails. it just provides a link on  the function.
This patch gets the text after the closing bracket and appends it at the end of  JavaDocConverter::convertLink function
