TST: fix wrong minpos expectation in test_relim_collection

tinezivic · tinezivic · commit ee070e3da0bd · 2026-04-21T00:37:12.000+02:00
Line data [0, 1] x [0, 1] gives minpos=[1., 1.] (minimum *positive*
value), not [inf, inf].  The [inf, inf] sentinel only appears when
there are no positive values at all.
