Results consistency

[rafamanzo]

We should ensure produced results are consistent within the database:

• Validations
  • [ ] Validate ModuleResult presence within a MetricResult
  • [ ] Validate ROOT ModuleResult presence within a Processing
  • [ ] Validate Processing presence within ModuleResult
  • [ ] Validate Processing presence within ProcessTime
  • [ ] Validate Repository presence within Processing
  • [ ] Validate Project presence within Repository
• [ ] Check those new requirements do not raise new issues, if they raise deal with them
