This PR removes the argument renumbering 0 -> 1 in the primal expression if V is a FunctionSpace. Thus if you want to interpolate an expression containing arguments (for example if you want to assemble the interpolation operator) then you need to use a
TrialFunctioninstead of aTestFunction. Recent UFL changes check the argument numbering and raise an error early to avoid confusion.This is an API change and should be merged after the next release. PR #4572 warns users about this.
