Sums in as_vector/as_matrix

[Guennel Andreas]

The following UFL-code generates an error: "UFLException: All terms in form must have same rank."
It seems that sums in as_vector and as_matrix cause this problem. (Version 0.9.9)

# UFL to test sums in as_matrix or as_vector
# Compile this form with FFC: ffc -l dolfin as_matrix.ufl

def test_vector(u):
    return as_vector([ u[0]+u[1], u[1] ])

def test_matrix(u):
    return as_matrix([[ u[0]+u[1], u[1] ]])

element = VectorElement("Lagrange", triangle, degree=1, dim=2)

# test and trial functions
u = TrialFunction(element)
v = TestFunction(element)

# variational problem: Linear form
L = inner( test_vector(u), test_vector(v) ) * dx
#L = inner( test_matrix(u), test_matrix(v) ) * dx

Problem seems to be handling of u[0] + u[1] in as_vector.

Seems like this no longer applies, looks like a duplicate of other fixed bugs.
