log: fix status template to list copy source per dest (issue5155)

Before, copied files were assumed as "A" (added) and listed followed by
non-copy added files. This could double entries of a copy if it had "M"
(modified) state.

So, this patch makes the template check if a file is included in copies dict.
This way, entries should never be doubled.

The output of "log -Tstatus -C" does not always agree with "status -C --change"
due to the bug of "status", which is documented in test-status.t. See also
2963d5c9d90b.

 Other "bug" highlight, the revision status does not report the copy information.
 This is buggy behavior.
