_grantRole in AccessControl.sol is private

_grantRole(DEFAULT_ADMIN_ROLE, root);

_grantRole() in AccessControl.sol is current private, so cannot be called by child contracts.

Hierarchy.sol is implemented using the 3.0.0-rc.0 version of AccessControl.sol, in which _grantRole() was still internal. We have PR #295 to migrate to 3.0.0-rc.1, in which we have this issue. I'll replace every call to _grantRole in a constructor by a call to _setupRole.

I think all the other calls to _grantRole can be replaced by calls to the public one, grantRole.

Am I missing anything?
