[REG 4.4->4.5] Configuration clone is broken

This is probably caused by 890c1906e6fb2eceb3eaf381b0c298138be3a932.

If you clone a Run Configuration with command line arguments or non-default Run in Terminal setting, it is lost in the cloned configuration.

From what I see, IRunConfigurationFactory::cloneHelper creates a new RunConfig, which initializes all aspects. Then the old aspects are cloned and appended to this RunConfig, so it has 2 aspects of the same type.

This looks related to QTCREATORBUG-19186.
