target key doesn't work in component hashes

[dhollinger]

The target key in a component hash (templates, actions, modules, etc) doesn't properly work when overridden.

If target is not supposed to be configurable at the component level

No error message is displayed, the component defined in the hash simple doesn't get created due to the lack of a parent concat resource that matches the concat::fragment's target attribute.

If target is supposed to be configurable at the component level

No parent concat resource exists for the concat::fragment that is generated, thus the config is not generated in a configuration file.
