largefiles: prevent committing a missing largefile

Previously, if the largefile was deleted at the time of a commit, the standin
was silently not updated and its current state (possibly garbage) was recorded.
The test makes it look like this is somewhat of an edge case, but the same thing
happens when an `hg revert` followed by `rm` changes the standin.

Aside from the second invocation of this in lfutil.updatestandinsbymatch()
(which is what triggers this test case), the three other uses are guarded by
dirstate checks for added or modified, or an existence check in the filesystem.
So aborting in lfutil.updatestandins() should be safe, and will avoid silent
skips in the future if this is used elsewhere.

  adding baz

close one of the heads
