largefiles: fix commit of missing largefiles

832c98d79587 improved merging of standin files referencing missing largefiles.
It did however not test or fix commits of such merges; it would abort.

To fix that, change copytostore to skip and warn about missing largefiles
with a message similar the one for failing get from remote filestores. (It
would perhaps in both cases be better to emit a more helpful warning like
"warning: standin file for large1 references 58e24f733a which can't be found in
the local store".)

To test this, make sure commit doesn't find the "missing" largefile in the global
usercache. For further testing, verify that update and status works as expected
after this.

This will also effectively backout 63116d47cc3f.
