Low level call in Address.sendValue(address,uint256) (#141-147):

Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

UpgradeableProxy.constructor(address,bytes)._logic (#255) lacks a zero-check on :
- (success) = _logic.delegatecall(_data) (#260)
Check that the address is not zero.
