[MEX-410] position creator with EGLD

[claudiulataretu]

Reasoning

• position creator transactions with EGLD and single token have different behaviour between consolidation of a position or create a new one

Proposed Changes

• add wrap EGLD only for position creator transactions with position consolidate
• use value for position transactions with EGLD and no consolidation

How to test

query CreateStakingPositionSingleToken {
	createStakingPositionSingleToken(
		stakingAddress: <staking_address>,
		payments: [{
 			amount: "1000000000000000000",
 			nonce: 0,
 			tokenID: "EGLD"
		}],
		tolerance: 0.01
	) {
		receiver
		value
		data
	}
}

• query should return one transaction with value

query CreateStakingPositionSingleToken {
	createStakingPositionSingleToken(
		stakingAddress: <stake_address>,
		payments: [{
 			amount: "1000000000000000000",
 			nonce: 0,
 			tokenID: "EGLD"
		},
		{
 			amount: "1000000000000000000",
 			nonce: <nonce>,
 			tokenID: <farm_stake_token_id>
		}],
		tolerance: 0.01
	) {
		receiver
		value
		data
	}
}

• query should return 2 transactions with EGLD wrap
