Remove year old pending blank tests

The nightly tests show over 2 pages of "pending" test.

It has been over a year since these TODOs were written. Do we think we going will circle back and implement these?

If so, I can add yours back - if not, I just want to remove them.

/cc @Fryguy @chessbyte @tinaafitz @martinpovolny ok to remove your blank tests?
