paul luse a3facce53c Fix invalid frag_index header in ssync_sender when reverting EC tombstones 
Back in d124ce [1] we failed to recognize the situation where a revert
job would have an explicit frag_index key wth the literal value None
which would take precedence over the dict.get's default value of ''.
Later in ssync_receiver we'd bump into the ValueError converting 'None'
to an int (again).

In ssync_sender we now handle literal None's correctly and should
hopefully no longer put this invalid headers on the wire - but for belts
and braces we'll also update ssync_receiver to raise a 400 series error
and ssync_sender to better log the error messages.
