fisher: Failed update leads to disappeared fisher

Sometimes with bad network, fisher update fails, and that leads to disappeared fisher and other installed plugins.

When the update fails, fisher complains like this (you can see the prompt changed from tide to fish default because tide was gone):

My guess is that “old” copies were deleted regardless of the download, but haven’t digged into that chunk of “eval” code to confirm it.
