Bugs related to mrp_production_real_cost and mrp_production_stimated_cost

[anajuaristi]

Testing the last versions of those modules I could find the following errors on them

1. The button "upload cost" to product is uploading the price negative (-206.60) to product form. It should be positive (206.60)
2. Real cost is informing the fields avg_cost and manual_stimated_cost in analytic line. This is incorrect. They should be zero. Real cost must assing a value only in field amount on analytic line. Otherwise it's duplicating the stimated cost.
   This was working before. The bug has been introduced on a merge made on summer or september.
3. Created final product related quant value is cero. It should be the total real cost(sum amount) / produced units. The final product related move has got a value on price_unit field. It seems that is not copied on quant cost field,

I still need to test more. But It's quite urgent we solve these bugs asap.
Thank you:

Sorry.
