replay: always fetch the entire first revision

The entire revision is fetched using the just-added get_revision()
wrapper.

Essentially, this allows us to begin a conversion with a non-zero
start revision. As an extra safety feature, this mode is *always* used
for the very first revision, even if no start revision is
specified. For most repositories, this shouldn't matter; the entire
revision will be fetched regardless. However, there are repositories
that currently `confuse' us, such as bzr-svn conversions, and where
this is an improvement.
