[Audit Fix] ElasticDAO.onlyAfterTokenInitialized duplicate _getEcosystem

[dmvt]

  modifier onlyAfterTokenInitialized() {
    Ecosystem.Instance memory ecosystem = _getEcosystem();
    bool tokenInitialized =
      Token(_getEcosystem().tokenModelAddress).exists(
        ecosystem.governanceTokenAddress,
        ecosystem.daoAddress
      );
    require(tokenInitialized, 'ElasticDAO: Please call initializeToken first');
    _;
  }

Definition of Done

• _getEcosystem is only called once
