fix CLI completion for ebook-convert

Browse source 
msgpack.loads will produce mutable, unhashable lists by default when
unpacking values that were originally saved as dicts with tuple
keys. Which ebook-convert-complete does. This results in errors when
trying to reassemble the dict.

Fix by allowing our msgpack wrapper to forward arguments, and by having
ebook-convert-complete unpack lists as tuples.
