ReducedFunctional's taylor_test doesn't honour InitialConditionParameter(str)

[Patrick Farrell]

I tried the new taylor_test method of the ReducedFunctional in tyamabe.py:

Traceback (most recent call last):
  File "tyamabe.py", line 39, in <module>
    jm.taylor_test(seed=0.01)
  File "/home/pef/src/dolfin-adjoint/dolfin_adjoint/reduced_functional.py", line 91, in taylor_test
    m_array = get_global(m)
  File "/home/pef/src/dolfin-adjoint/dolfin_adjoint/optimization.py", line 35, in get_global
    raise TypeError, 'Unknown parameter type %s.' % str(type(m))
TypeError: Unknown parameter type <type 'str'>.

It is caused by the ReducedFunctional being created with InitialConditionParameter("Solution").
