Re-register the composer autoloader so that Resque from _this_ repo is used and not another version from APP_INCLUDE.

Requiring composer from external apps causes their autoloader to register
which takes precedence over any prior registered autoloaders.

This may cause issues when using an APP_INCLUDE that depends on an older
version of Resque which ends up replacing this version.
