referring to the discussion in #6608 .

When a singular matrix assembled for StandardWell, we should not create an identity matrix as a inverse to continue.

With #6608 merged, the singular matrix from StandardWell assembling during well testing from all the regression tests looks like gone, this PR does not introduce any regression failures.

This also makes the processing of the singular well matrix consistent between StandardWell and MultisegmentWell.

Great! The jenkins is green, which means the several regression failures earlier (around 6 or 7) are all related to / fixed through #6608 .

Will clean up this PR and hopefully get it merged.
