Don't simplify template for class names in declarations (#3505) 
* Don't simplify template for class names in declarations

Without the patch, the test would give:

```
Expected:
namespace foo { class Bar ; } class Baz ; class C : Baz { } ;

Actual:
namespace foo { class Bar ; } class Baz ; class foo :: Bar : Baz { } ;

```

* Use valid code in test case

Fix handling of namespace scope with several bodystarts (#3438) 
Follow up to 0093452bed.
Give the proper end to getVariableList, since it might not be bodyEnd.

Before that, getVariableList would add the same variables in several
unrelated scopes, and all kind of false positive would follow.

For instance, with the case I added in the unit-tests, I had:
```
../code.cpp:15:18: warning: The struct 'is_A' defines member variable with name 'foo' also defined in its parent struct 'is_A_impl'. [duplInheritedMember]
static const int foo = 8;
