Repeated functions / Syntax error.

The patch from #1517066: Implement hook_hook_info() introduced a php syntax error since the following functions are repeated:

/**
 * Let other modules do things before default entities are created on revert.
 */
function hook_uuid_entities_pre_rebuild($plan_name) {

}

/**
 * Let other modules do things after default entities are created on revert.
 */
function hook_uuid_entities_post_rebuild($plan_name) {

}

If I understand correctly those hooks should be pre_revert and post_revert so I've attached a patch to fix that.

Note that this is currently breaking the test on the test bot for this module.

Cheers.
