Fix issue 1470, which is that if either apr_uid_current() or apr_uid_name_get() fail, svn returns a fatal error.  This prevented svn from working on Win98 against a password-protected repository (without sneaky workarounds).

Note: I have not actually tested this on Win98, but this change works when
I simulate failure of apr_uid_current() on my test machine.
