When do we end up resolving a URI against a relative URI? I thought we always
started with an absolute URI.

For summaries we resolve relative URIs against relative URIs.  It's possible
that this is unnecessary (some things about URI handling have changed since the
initial design of summaries).  I will look into whether it's possible to stop
doing this.

After further investigation, I believe it is still necessary.  See my comments
on https://github.com/dart-lang/sdk/issues/27447 for a specific example.
