[ibis] geo_equals() got an unexpected keyword argument 'cache'

from Todd:
hit an error in ibis with this expression
t[t.omnisci_geo.point_n(point_idx).x().name('point_a_x'), t.omnisci_geo.point_n(point_idx).y().name('point_a_y'), t.omnisci_geo.point_n(point_idx+1).x().name('point_b_x'), t.omnisci_geo.point_n(point_idx+1).y().name('point_b_y')].execute()

which gets called via all_equals in ibis/expr/operations.py, i assume ibis is trying to helpfully dedup projections?
