Improve muzzle check for constructors #4591

Muzzle should fail if our helper class references a library base class constructor that's absent on the classpath. For example imagine that muzzle codegen has captured references to the following class hierarchy: Helper extends LibraryBaseClass extends Object, all with default no-arg constructors. Now, if the actual LibraryBaseClass on the application classpath had a constructor that requires a long the muzzle check would still pass - because it would find the default constructor in the Object class. This PR fixes muzzle so that it recognizes this situation.
