Fix warning about converting false to pointer type.

The following warning is produced by certain versions of gcc 4.5:
sitkMorphologicalWatershedImageFilterTest.cxx:188:3: warning:
converting 'false' to pointer type for argument 1 of 'char
testing::internal::IsNullLiteralHelper(testing::internal::Secret*)

for google test to use the ASSERT_FALSE methods.
