fix(fuse): never adopt a node we trashed as an unanswered create's twin (B162)

A folder removed and made again met the old folder while its trash was on
the wire and adopted it, so the new folder's contents went into the old
one and were trashed with it. The twin search now skips hidden nodes, as
listings do.

The fake Drive can hold a trash (hold_next_trash).
