Revert of git_auto_svn.py: Rewrite http SVN URLs to https

Revert of git_auto_svn.py: Rewrite http SVN URLs to https (patchset #3 id:40001 of https://codereview.chromium.org/745473003/)

Reason for revert:
This actually makes the Git mirrors unusable for git svn, since there's a mismatch between the svn remote URL and the URLs of the git-svn-id footers in each Git commit (which confuses scripts like git_cl.py and makes uploading and committing CLs impossible).

Original issue's description:
> git_auto_svn.py: Rewrite http SVN URLs to https
> 
> BUG=435091
> TESTED=Ran the following:
> git clone https://chromium.googlesource.com/external/webrtc
> cd webrtc
> git auto-svn
> cat .git/config
> Verified the URL was using http before this patch, and https after applying it.
> 
> R=agable@chromium.org, mmoss@chromium.org

Presubmit checks took 120.4s to calculate.

Was the presubmit check useful? If not, run "git cl presubmit -v"
to figure out which PRESUBMIT.py was run, then run git blame
on the file to figure out who to ask for help.
