Precompile doesn't appear to work on Sprockets 3 (Rails 5)

[thegillis]

The mechanism for lookup up precompiled assets and logical names appears to have changed significantly in Sprockets 3. Calls such as each_logical_path do not even exist any more.

I'll attempt to submit a pull request shortly with a potential fix after I verify my change is working on our system.

In case anyone else is in immediate need for getting this to work, my work in progress is at:
