fetch: die on invalid --negotiation-tip hash

If a full hexadecimal hash is given as a --negotiation-tip to "git
fetch", and that hash does not correspond to an object, "git fetch" will
segfault if --negotiate-only is given and will silently ignore that hash
otherwise. Make these cases fatal errors, just like the case when an
invalid ref name or abbreviated hash is given.

While at it, mark the error messages as translatable.
