New feature allowing to disable sending FT to smart contracts

[wojtek-coreum]

Description

Reviewers checklist:

• Try to write more meaningful comments with clear actions to be taken.
• Nit-picking should be unblocking. Focus on core issues.

Authors checklist

• Provide a concise and meaningful description
• Review the code yourself first, before making the PR.
• Annotate your PR in places that require explanation.
• Think and try to split the PR to smaller PR if it is big.

x/asset/ft/keeper/before_send.go line 182 at r1 (raw file):

func (k Keeper) isSmartContract(ctx sdk.Context, addr sdk.AccAddress) bool {
	return len(addr) == wasmtypes.ContractAddrLen

&& k.wasmKeeper.HasContractInfo(ctx, sender) is removed from here because when tokens are attached to the smart contract instantiation, at this stage HasContractInfo still returns false
