Fixed issues when running Unit tests and Behat:

    Declaration of moodle1_mod_url_handler::process_legacy_resource() should be compatible with
    moodle1_resource_successor_handler::process_legacy_resource(array $data, array $raw = NULL)

    $defaultEchoSystemMoodleExternalIdOption fixed to be key of Options array from 1.

    Fatal error: Class 'moodle_echolink' not found

       moodle1_convert_exception: error/missing_handler_class
