symboldatabase: Fix potential null pointer dereference (#1072) 
There is a  potential `nullPointer` dereference in symboldatabase. This PR attempts to fix this. Additionally, this could be detected by Cppcheck as well. 

Here is a reduced and compilable testcase, where Cppcheck fails to detect a potential `nullPointer` dereference:

```
class Scope
{
public:
    bool bar();
    int *definedType;
};

int f(Scope *new_scope)
{
    int ret = 1;
    if (new_scope)
    {
        if (new_scope->bar())
        {
            if (!new_scope->definedType) {} // check for null
            ret = *new_scope->definedType; // dereference
        }
    }
    return ret;
}
```
