    [facet][box] do not use modified elembctypes · 4e4c35d6

    This commit also modifies the tracer_tracer test, as this failed for box
    after removing the elembctypes. This is because it was using Neumann
    no-flow boundary conditions for the fracture domain on the left boundary
    while the bulk problem used Dirichlet BCs. The old elembctypes for box
    were discarding Dirichlet BCs on those nodes on the boundary that also
    couple to fractures in order for the coupling conditions to be
    fulfilled. However, that discards the boundary condition. With this
    commit, Dirichlet BCs are always fulfilled, but for the tracer test this
    means that as a consequence, the pressure in the fracture on the left
    side is equal to the bulk pressure - because it uses Dirichlet-type
    coupling conditions. This commit changes the test such that it uses
    Dirichlet BCs in the bulk domain only on the lower part of the boundary
    such that the fracture touches the domain boundary at a no-flow
    boundary.
