fix(fuse,core): keep a rename made while its create is on the wire

A rename of a node whose create is still queued rewrites the create's
target, but the drain had already copied the op. When the create
landed, the row was deleted unread and the rename was lost (B136).

finish_create now learns where the create was sent and where it landed,
and queues a rename of the real uid when the row has moved on since.
adopt_real_uid keeps the tree's name and folder while that rename is
queued. A landed folder's children also stop naming its placeholder as
their parent in memory, which put the placeholder back on their rows.
