Pass the passed in context into some nested function calls, wrap
errors instead of %+v, and change some tests to strictly just test
for an error and not an exact error.

The reference/docker package was a fork of github.com/distribution/distribution,
which could not easily be used as a direct dependency, as it brought many other
dependencies with it.
The "reference' package has now moved to a separate repository, which means
we can replace the local fork, and use the upstream implementation again.
The new module was extracted from the distribution repository at commit:
