* Fix tests due to upstream change
Odoo has added a constraint for avoiding a company currency change if there
are move lines, making these tests to fail, as the currency is changed to EUR.
With this commit, we create a new company with EUR currency for avoiding the
problem.
This commit also changes account_banking_mandate for not duplicating mandate
number, as it was detected during the test creation.

* Avoid errors in tests when run with other modules
* More adaptations to make tests to work properly
All these problems comes from using demo data.
