git status: refresh the index if possible

This was already the case before commit 9e4b7ab6 (git status: not
"commit --dry-run" anymore, 2009-08-15) with the difference that it died
at failure.
It got lost during the new implementation of "git status", which was
meant to only change behaviour when invoked with arguments.
