[SWIP-28] Fix Corner Case Related To Exit Queue In Vaults v3

In this proposal, we are requesting the DAO's approval for minor changes to the exit queue logic to fix a corner case in the exit queue index calculation. In some cases, exit queue positions that were processed but not claimed in v2 vaults may become unclaimable in v3 vaults. These changes have been approved by Sigma Prime, who previously audited most of the StakeWise smart contracts.

See the full details of the proposal in the forum link below.
