empty triangulation: expected at least one max simplex w/ older TOPCOM

The builds for Macaulay2 1.26.06 are currently failing on several older Debian (bullseye) and Ubuntu (focal/jammy) systems which still have TOPCOM 0.17.8:

Start with the failing tests in Triangulations.m2 at lines 3080-3112 and 3738-3826, and reproduce them on a system using TOPCOM 0.17.8. Compare the failing allTriangulations calls with the full build log and determine what is needed for tests 7 and 21 to pass on older Debian and Ubuntu systems.
