largefiles: distinguish "no remote repo" from "no files to upload" (issue3651)

Before this patch, when no files to upload, "hg outgoing --large" and
"hg summary --large" show "no remote repo", even though valid remote
repository is specified.

It is because that "getoutgoinglfiles()" returns None, not only if no
valid remote repository is specified, but also if no files to upload.

This patch makes "getoutgoinglfiles()" return empty list when no files
to upload, and makes largefiles show "no files to upload" message at
that time.

This patch doesn't test "if toupload is None" route in
"overrideoutgoing()", because this route is not executed unless remote
repository becomes inaccessible just before largefiles specific
processing: successful execution of "orig()" means that at least one
of "default", "default-push" or dest is valid one, and that
"getoutgoinglfiles()" never returns None in such cases.

At "hg summary --large" invocation, this patch shows message below:

    largefiles: (no files to upload)

This follows the message shown by "hg summary" with MQ:

    mq:     (empty queue)
