Patch: fix bs get_decoded_stream

[José Dapena Paz <jdapena igalia com>]

	Hi,

	This is the first fix for regression caused by bodystruct support ;).
We were getting the tny_camel_bs_mime_part_get_decoded_stream stream in
eos position, instead of in a way we could start getting its
information.

	So now, we do a reset before returning it to caller.
