…ndings on MACI

Implemented fixes for audit findings on MACI, Poll, VkRegistry and AccQueue. 1. Fixed possible
reentrancy attacks. 2. Moved around error messages to reflect the correct error condition.  3.
changed storage variables outside of loops to reduce gas costs. 4. Added SafeERC20 to check a
transfer's return value. 5. Removed redundant boolean checks. 6. Using return value of
`maci.mergeStateAq` to update the `mergedStateRoot` variable.
