Warning for documented return of void type function

In case a void type function is documented it is not allowed to used a `\return` or `\retval` command. The test was present but not correct
- test on `g_hasReturnCommand ` which signals whether of not `\ret...` is used instead of  `g_memberDef->hasDocumentedReturnType()`
- removed test on emty return type (empty return type is assumed to be non void, see e.g. C, Fortran).
- order of the tests is important
