Broken repository_id action for MetricResult controller

[diegoamc]

Currently, we try to call a MetricResult#processing method.

The problem is that method does not exist. We don't have any database associations neither.

Since TreeMetricResult and HotspotMetricResult controllers both inherit from MetricResult controller (and they also don't have the processing method implemented), that action will break for them too.

Maybe it is the case of evaluating if we really need that action, before implementing it.

I have the feeling this action is one of the kind we envisioned years ago that would simplify a lot the requests. I think it is a good one and is just a question of we fixing it and using it!
