Move documentation of MatrixBase methods in MatrixFunctions to module page.
...
I think that because MatrixFunctions is in unsupported/ and MatrixBase is
not, doxygen does not include the MatrixBase methods defined and documented
in the MatrixFunctions module with the other MatrixBase methods. This is a
kludge, but at least the documentation is not lost.

The latter is more stable. This fixes one of the issues with the test.
