# Description
This fixes the duplication error when the same deal has more than one contact. Impact was not massive, it just affected because of the Home to Host account and this has happened during the past week. There were other cases that contained duplicates but these were not invoiced so it didn't affect the total sum.
Changes:
* Contacts now has a boolean field indicating if a deal exists.
* Contacts now has a boolean field indicating if that contact has a deal informed and it's the last updated one. This is opinionated - it could have been done with creation, for instance.
* Sales monthly trends forces the last updated contact to be true.
* Improved robustness by adding tests.
Note that modifying the logic in intermediate on `int_xero__sales_monthly_trends` by changing `id_deal` per `id_contact` would not have worked - we need to do this compute by deal to ensure that any invoicing is reported MoM and YTD.

# Description
New model that aggregates in a monthly basis the information from Xero sales. The aggregation is done by several categories, most of them to be included as filters in PBI. Metrics represent the amount without taxes in: 1) the current month, 2) the previous month, 3) twelve months ago, 4) current year YTD (fiscal year) and 5) previous year YTD (fiscal year).
It also propagates the model to reporting

- [ ] I've picked the right materialization for the affected models. **I was hesitating between table or view. Table should speed up tests, but I intend to create a reporting table with a similar structure so probably a bit of waste of space. Anyway, not a big deal now**
