Test for TriangularView<Strictly*> with a sparse matrix

Dear Eigen developers, 

when used with a sparse matrix, TriangularView<StrictlyLower> and TriangularView<StrictlyUpper> also extract the diagonal of the matrix although StrictlyLower and StrictlyUpper should only consider the lower/upper triangle without the diagonal.

The same code works when a dense matrix is considered.
