lfs: add note messages indicating what store holds the lfs blob

The following corruption related patches were written prior to adding the user
level cache, and it took awhile to track down why the tests changed.  (It
generally made things more resilient.)  But I think this will be useful to the
end user as well.  I didn't make it --debug level, because there can be a ton of
info coming out of clone/push/pull --debug.  The pointers are sorted for test
stability.

I opted for ui.note() instead of checking ui.verbose and then using ui.write()
for convenience, but I see most of this extension does the latter.  I have no
idea what the preferred form is.
