Unable to create as_multi calls due to encoding rules of OpaqueCall's #20
Description
Currently the encoding rules for as_multi require the call to be serialised:
as_multi = ScaleDecoder.get_decoder_class("Call", metadata=kusama.metadata)
transfer = ScaleDecoder.get_decoder_class("OpaqueCall", metadata=kusama.metadata)
transfer.encode(
{
"call_module": "Balances",
"call_function": "transfer",
"call_args": {"dest": "CofvaLbP3m8PLeNRQmLVPWmTT7jGgAXTwyT69k2wkfPxJ9V", "value": 10000000000000},
}
)
as_multi.encode(
{
"call_module": "Multisig",
"call_function": "as_multi",
"call_args": {
"call": str(transfer),
"maybe_timepoint": {"height": 3012294, "index": 3},
"other_signatories": sorted(['D2bHQwFcQj11SvtkjULEdKhK4WAeP6MThXgosMHjW9DrmbE', 'CofvaLbP3m8PLeNRQmLVPWmTT7jGgAXTwyT69k2wkfPxJ9V']),
"threshold": 2,
"store_call": True,
"max_weight": 10,
},
}
)
However, presumably due to a metadata change, the same parameter is now only accepted in dictionary format:

TypeError: string indices must be integers

I submitted a PR with one patch for the error, but ideally this could be handled at the point of as_multi encoding
