Hey,

My tog started dying like this

	$ tog 
	tog: GOT_AUTHOR environment variable is not set

This started happening with a66bb113790d6808d3a1646844962ac4d5153dec .
tog_worktree_status exits with an error if it doesn't manage to find an
author. This is easily reproducible by running tog in a dirty worktree
from a cloned repo while GOT_AUTHOR is unset.

The following patch addresses that, by setting wt_author to "". I don't
consider the situation should be fatal for this purpouse.

btw, I think that wctx->wt_author leaks? I couldn't convince myself that
tog_worktree_status is called only once before worktree_ctx_close.

comments? oks?

 repository while GOT_AUTHOR is unset.
