Issue:
Once we initially approve our contract to engage with the smart contract, the approve contract message shouldn't show and request another approval.
Acceptance Criteria:
WHEN a user has approved a their GTC to be used on the Staking Smart Contract
AND they click "Modify Stake" to see their staking
THEN they should see how much GTC they have staked reflected in the input field
AND they should not see a message prompting them to approve GTC to interact with the smart contract a second time
