CREDENTIAL: Convert federations from URLs to origins throughout.

We've been loosely treating federations as URLs, as it was simple and
easy. That laxness, however, has caused some issues with the Android
integration, as they are doing exact string comparisons as opposed to
origin comparisons. In particular, they expect the serialization stored
to sync to exclude the trailing '/'.

This patch converts the field to an origin throughout, which ensures
both that the serialization matches Android's expectations, but also
that we're properly excluding paths and etc. from the comparisons we
make in various places in the codebase.
