shiboken: Improve handling of pointer types for CONVERTTOCPP in injected code

Code snippets like:
QByteArray *cppSelf = %CONVERTTOCPP[QByteArray *](obj);

cause an assert in shiboken since the '*' is captured into
the target of the assignment and is not considered part of the type.

Make the error message a bit clearer and add documentation.
