Invalid array key

[zaerl]

On DoctrineMongoDBExtension::normalizeDriverOptions:319 we have typemap (as well as on all tests) but on ext-mongodb Client class constructor the key is typeMap. This generate various problems with array type hints on Doctrine\ODM\MongoDB\UnitOfWork:getOrCreateDocument for example which expect an array but get a MongoDB\Model\BSONArray (which is the default and is not an array).

A var_dump of generated option:

Array
(
    [typemap] => Array
        (
            [root] => array
            [document] => array
        )
    [typeMap] => Array
        (
            [array] => MongoDB\Model\BSONArray
            [document] => MongoDB\Model\BSONDocument
            [root] => MongoDB\Model\BSONDocument
        )
)

Change row 319 to:

$driverOptions['typeMap'] = ['root' => 'array', 'document' => 'array'];

and the problem is solved.

@alcaeus: This does look like a typo in the bundle. The correct option name is typeMap in $driverOptions.

Thanks.
