Unstake button doesn't chagne to withdraw immediately after unstake

[evanpipta]

There's a small delay after approving the unstake transaction where you can click the unstake button again, even though the transaction may still go through.

This should be fixed and the unstake button shouldn't be available until after the user's position has updated in the UI.
