Failing genesis

[kamilsa]

If we take latest substrate and generate genesis using commands:

./target/debug/substrate build-spec --chain=local > ~/localspec.json
./target/debug/substrate build-spec --chain ~/localspec.json --raw > ~/localchain.json 

and then pass this genesis to the latest kagome:

cd node/
kagome_validating --genesis ~/localchain.json --keystore localkeystore.json -l sub_ldb1 --p2p_port 11122 --rpc_http_port 11133 --rpc_ws_port 11144 -f -v 0

Then we can see the error: message: panicked at 'Host to wasm values are encoded correctly; qed: Error' thrown when BabeApi_configuration is invoked

Checked also using polkadot.json from https://github.com/paritytech/polkadot/blob/master/service/res/polkadot.json.
Hash of block is the same, but error remains

This is the list of apis executed during BabeApi_configuration before the error is thrown:

This PR checks that allocator apis are working fine

Things that should be fixed:

• Fix ext_storage_read Fix ext_storage_read_version_1 #520
• Add ext_storage_append ext_storage_append #521
