svn.loader: Uncompress the tarball during the `prepare` call

Antoine R. Dumont requested to merge generated-differential-D434-source into generated-differential-D434-target

Prior to this commit, the uncompression step happened in the init call. Now, this happens in the prepare method.

This allows to have 'partial' visit if something wrong happens during uncompression step (against nothing at the moment).

This is symmetric to what we do with the mercurial loader (HgArchiveBundle20Loader [1]).

Test Plan

Use toplevel and load a repository dump. All should be fine.

cf. README.md adaptations (D434#change-e9wbZ9Ppa6Oy) which demonstrates such use case ;)

$ python3
>>> repo = '0-512-md'
>>> archive_name = '%s-repo.svndump.gz' % repo
>>> archive_path = '/home/storage/svn/dumps/%s' % archive_name
>>> origin_url = 'http://%s.googlecode.com' % repo
>>> svn_url = 'file://%s' % repo
>>>
>>> import logging
>>> logging.basicConfig(level=logging.DEBUG)
>>>
>>> from swh.loader.svn.tasks import MountAndLoadSvnRepository
>>>
>>> t = MountAndLoadSvnRepository()
>>> t.run(archive_path=archive_path,
...       origin_url=origin_url,
...       visit_date='2016-05-03T15:16:32+00:00',
...       start_from_scratch=True)
