Tpetra::RowMatrixTransposer does not sort rows

Created by: ndellingwood

@trilinos/tpetra @mhoemmen

The CrsMatrix path of Tpetra::RowMatrixTransposer::createTransposeLocal does not sort rows in the local_matrix_type, yet it passes the local_matrix_type to CrsMatrix's constructor. The latter assumes that the rows are sorted. This causes problems downstream. I have a small reproducer that I need to clean up, but @mhoemmen has a solution in mind.
