convergence writer

- The residual calculation for el2p was wrong, probably never used. It now
  forwards the call to the GridOperator functionality.

- The multidomain convergence writer assumed that sub-domain solution
  vectors can be default-contructed. This is not the case if a PDELab
  model is used for the subdomain.

The two-phase geomechanics model is based on PDELab 2.0 now. In order to
avoid patching, the ElTwoPModel is based on the new ElTwoPBaseModel
instead of the ImplicitModel. The ElTwoPBaseModel is almost a copy of
ImplicitModel and only differs in the way that the SolutionVectors are
handled. There's definitely room for improvement here.
