update: fix bare update to work on new branch

So far bare update on new branch results in
'abort: branch new-branch not found'. This commit fixes
this by updating to the parent of wctx.

The effect of updating to the parent of wctx is to move to the paren't
branch - this means that it is no longer necessary to prevent you from
updating if you would lose your newly created branch.
