Fix WorkspaceId injection for RepositoryDAOImpl

Previously it was being injected per Dao Module which is wrong
given that now we can one workspace per execution or MasterModule
So instead moved it to MasterModule using the same workspace vars
making it possible to override workspace using System Properties
