Initialization flaws
For non-upgradeable contracts, the Solidity compiler takes care of chaining the constructor calls of an inheritance hierarchy in the right order; for upgradeable contracts, taking care of initialization is a manual task - and with extensive use of inheritance, it is tedious and error-prone. The convention in OpenZeppelin Contracts Upgradeable is to have a `__C_init_unchained` function that contains the actual initialization logic for contract `C` and a `__C_init` function that calls the `*_init_unchained` function for every super-contract - direct and indirect - in the inheritance hierarchy (including C) in the C3-linearized order from most basic to most derived. This pattern imitates what the compiler does for constructors.\\nAll `*_init` functions in the contracts (__ERC20WrapperGluwacoin_init, `__ERC20Reservable_init`, `__ERC20ETHless_init`, and __ERC20Wrapper_init) are missing some `_init_unchained` calls, and sometimes the existing calls are not in the correct order.\\nThe `__ERC20WrapperGluwacoin_init` function is implemented as follows:\\n```\\nfunction \\_\\_ERC20WrapperGluwacoin\\_init(\\n    string memory name,\\n    string memory symbol,\\n    IERC20 token\\n) internal initializer {\\n    \\_\\_Context\\_init\\_unchained();\\n    \\_\\_ERC20\\_init\\_unchained(name, symbol);\\n    \\_\\_ERC20ETHless\\_init\\_unchained();\\n    \\_\\_ERC20Reservable\\_init\\_unchained();\\n    \\_\\_AccessControlEnumerable\\_init\\_unchained();\\n    \\_\\_ERC20Wrapper\\_init\\_unchained(token);\\n    \\_\\_ERC20WrapperGluwacoin\\_init\\_unchained();\\n}\\n```\\n\\nAnd the C3 linearization is:\\n```\\nERC20WrapperGluwacoin\\n  ↖ ERC20Reservable\\n  ↖ ERC20ETHless\\n  ↖ ERC20Wrapper\\n  ↖ ERC20Upgradeable\\n  ↖ IERC20MetadataUpgradeable\\n  ↖ IERC20Upgradeable\\n  ↖ AccessControlEnumerableUpgradeable\\n  ↖ AccessControlUpgradeable\\n  ↖ ERC165Upgradeable\\n  ↖ IERC165Upgradeable\\n  ↖ IAccessControlEnumerableUpgradeable\\n  ↖ IAccessControlUpgradeable\\n  ↖ ContextUpgradeable\\n  ↖ Initializable\\n```\\n\\nThe calls `__ERC165_init_unchained();` and `__AccessControl_init_unchained();` are missing, and `__ERC20Wrapper_init_unchained(token);` should move between `__ERC20_init_unchained(name, symbol);` and `__ERC20ETHless_init_unchained();`.
Review all `*_init` functions, add the missing `*_init_unchained` calls, and fix the order of these calls.
