Fix destructor name ...

Fix destructor name ...

There appears to be a pb in 9df8c9daf10ff30a8e6506b72406d032f268a17b.

For a template class, A::B::C<T1,T2>
the destructor name was C<T1,T2>
leading to code like
A::B::C<T1,T2>::~C<T1,T2>()

which does not compile on gcc (4.6, 4.7), also it seems to be correct code ...
clang and intel C++ compile it, but not gcc.

I changed the name to generate the code :

A::B::C<T1,T2>::~C()

which compiles on gcc, clang, intel

by further cutting the <...> in the destructor name.
