Unable to install with MySql 5.7

I am unable to install this module with MySql 5.7. The error returned is

PDOException: SQLSTATE[42000]: Syntax error or access violation: 1171 All parts of a PRIMARY KEY must be NOT NULL; if you need NULL in a key, use UNIQUE instead: CREATE TABLE {social_share_networks} ( `machine_name` VARCHAR(255) DEFAULT NULL, `human_name` VARCHAR(255) DEFAULT NULL, `url` BLOB DEFAULT NULL, `weight` INT NOT NULL DEFAULT 0, `locked` INT unsigned NOT NULL DEFAULT 0, PRIMARY KEY (`machine_name`) ) ENGINE = InnoDB DEFAULT CHARACTER SET utf8; Array ( ) in db_create_table() (line 2720 of /var/www/tcd-dev/includes/database/database.inc).

It is probably the same issue as found here https://www.drupal.org/node/2388139

I have fixed it locally with by adding the 'not null' => TRUE to the schema.
