Inconsistency between conseil.sql and database in the testing environment

[molowny]

Conseil creates DB schema from Slick table definition in the testing environment. It leads to the inconsistency in tables definitions and prevents from views usage. e.g.

• If we create NUMERIC field in conseil.sql, Slick will replace it with DECIMAL(21,2) in Table.schema
• If we create a view in conseil.sql, Slick will replace it with a TABLE in View.schema

Example of the problem: I had to set the difficulty to 16307.42 instead of 16307.42093852398 in DbFixtures only because Slick changed NUMERIC to DECIMAL(21,2)
