Sqlite Platform doesn't set a proper mapping for "double precision" to act as float.

I have a column in an entity, defined as "float" type.
When I run my phpunit tests (which are defined to use sqlite, whereas my production and development environment uses mysql), I get the following exception:

Doctrine\DBAL\DBALException: Unknown database type double precision requested, Doctrine\DBAL\Platforms\SqlitePlatform may not support it

Looking at AbstractPlatform.php, line 1972, function "getFloatDeclarationSQL" returns 'DOUBLE PRECISION'.
Where other platforms have in their "initializeDoctrineTypeMappings" method a mapping such as:

'double precision' => 'float',

, SqlitePlatform.php doesn't have such a mapping.
