No gesa2

[jajhall]

The unit test presolve-only-at-root added by @fwesselm used gesa2.mps, and took 3s in debug, increasing the run ime of bin/unit_tests by 15%.

Using rgn.mps exposes about as much use of the mip_root_presolve_only option as gesa2.mps, and the unit test is only 1.5s.

The test itself merely checks that Highs::run() returns HighsStatus::kOk so is of questionable value
