commerce_log crashes if commerce_cart is not enabled

I just updated to beta5, cleared cache, then I was going to enable commerce_log. When enable the module, the following error occurs:

The website encountered an unexpected error. Please try again later.

I don't have commerce_cart enabled. If this commerce_cart is an dependency, then we need to add it in commerce_log.info.yml; otherwise, there is more to fix.
