Fixed problems w/ 2nd repo init if first repo init had bad URL.

This is the simplest fix: if we had problems syncing the
manifest.git directory and we were the ones that created it,
we should delete it.  This doesn't try to do anything complex
like try to recover from a .repo directory that got broken in
some other way.

TEST=manual

Init once with a bad URL:
  $ repo init -u http://foobar.example.com
  Getting manifest ...
     from http://foobar.example.com
  Connection closed by 172.22.121.77
  error: Couldn't resolve host 'foobar.example.com' while accessing http://foobar.example.com/info/refs

  fatal: HTTP request failed
  fatal: cannot obtain manifest http://foobar.example.com

Init again: identical to the first.  Good:
  $ repo init -u http://foobar.example.com
  Getting manifest ...
     from http://foobar.example.com
  Connection closed by 172.22.121.77
  error: Couldn't resolve host 'foobar.example.com' while accessing http://foobar.example.com/info/refs

  fatal: HTTP request failed
  fatal: cannot obtain manifest http://foobar.example.com

Init with correct URL:
  $ repo init -u http://git.chromium.org/git/manifest -m minilayout.xml
  Getting manifest ...
     from http://git.chromium.org/git/manifest
  [ ... cut ... ]

  repo initialized in /.../repoiniterr

Try a bad URL after a good one; it doesn't get saved (good):
  $ repo init -u http://foobar.example.com
  Connection closed by 172.22.121.77
  error: Couldn't resolve host 'foobar.example.com' while accessing http://foobar.example.com/info/refs

  fatal: HTTP request failed
  fatal: cannot obtain manifest http://foobar.example.com

Just to confirm, I can still do a good one after a bad...
  $ repo init -u http://git.chromium.org/git/manifest -m minilayout.xml
