[PATCH v2] git svn: fix authenticaton with 'branch'

[Hiroshi Shirosaki <h.shirosaki@gmail.com>]

Authentication fails with svn branch while svn rebase and
svn dcommit work fine without authentication failures.

$ git svn branch v7_3
Copying https://xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx at r27519
to https://xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/v7_3...
Can't create session: Unable to connect to a repository at URL
'https://xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx': No more
credentials or we tried too many times.
Authentication failed at
C:\Program Files\Git\mingw64/libexec/git-core\git-svn line 1200.

We add auth configuration to SVN::Client->new() to fix the issue.
