[SYSTEMDS-3159] Fix rand boundary block handling in spark
The recently changed seed handling for ultra-sparse but also dense, and
sparse data generation revealed some hidden bugs. Specifically, in spark
there is a boundary block handling that converts the local block to
sparse if needed for consistency. Due to a missing flagging as sparse
the generated values on this special boundary blocks (e.g., the test had
a 1x1 boundary block) were ignored. The changed seed handling revealed
the issue because before we generated 0 for this boundary block.
Furthermore, there were some brittle tests that hard-coded results of
rand, which have been fixed as well.
