Validate resource in addPermissionToRole

[broom9]

When calling addPermissionToRole, if one of the resources is undefined, it would lead to an error

TypeError: Cannot read property 'split' of undefined
      at AccessAuthorizer.filterRelevantPermissions (node_modules/@bluejay/access-control/src/classes/access-authorizer.js:60:62)
      at AccessAuthorizer.authorize (node_modules/@bluejay/access-control/src/classes/access-authorizer.js:21:42)
      at AccessControl.<anonymous> (node_modules/@bluejay/access-control/src/classes/access-control.js:20:42)

You should be able to reproduce by codes like this:

store.addPermissionToRole('some_role', {
    id: 'read',
    effect: PermissionEffect.ALLOW,
    resource: [undefined],
    action: ['read']
  });
