Install file still creates wrong column (uid_invitee vs email_invitee)

According to the release notes from 5.x-0.5:

Made a semantic change in field names. uid_invitee was never right...we are storing email addresses in that varchar field

However, the .install file still creates a uid_invitee column, and there is no email_invitee column in the table. I patched it as follows, but am still testing my fix:

function node_invite_update_7() {
	$result = array();
	switch ( $GLOBALS['db_type'] ) {
		case 'mysql':
		case 'mysqli':
			$result[] = update_sql("
				ALTER TABLE {node_invites} CHANGE uid_invitee email_invitee VARCHAR(100) NOT NULL
			");
			break;
		default:
			drupal_set_message("Your database platform (" . $GLOBALS['db_type'] . ") is not supported by this module.");
	}
	return $result;
}

As it is, 5.x-0.5 doesn't work out of the box.

Then again, I'm new to Drupal, so forgive me if this isn't really a critical bug.
