[PATCH] git-remote: load config whenever create_symref() might be called

["Jérémie Detrey" <Jeremie.Detrey@altu.fr>]

Currently, the calls to `create_symref()` do not honor the
`core.logAllRefUpdates` nor the `user.{name,email}` configuration
settings, and therefore write reflogs even when explicitly asked not
to, and ignore the configured user identity.

This happens on `git remote add --fetch`, `git remote set-head`, and
`git remote rename`: these are the three commands which may create
a symbolic-ref for the remote's HEAD.

A call to `git_config(git_default_config, NULL);` for these three
commands is enough to load the necessary configuration beforehand.

The call to `git_config()` was inserted right after command-line
processing for these three commands. One might also decide to push
it closer to the actual call to `create_symref()`, as it is not
needed elsewhere, but it made more sense not to have it buried into
nested `if` conditions.
