[WASM] Some Runtime Tests fail on WASM

[davidjohnoliver]

These failures were uncovered by https://github.com/unoplatform/uno/pull/2301 - previously async tests weren't reporting failures.

• MeasureOverride_With_Nan_In_Grid(), Cannot measure [Windows.UI.Xaml.Controls.Grid] with NaN - added by https://github.com/unoplatform/uno/pull/2175

• When_MinWidth_SmallerThan_AvailableSize(), Assert.AreEqual failed. Expected:<[110;15]>. Actual:<[50;15]>. - added by https://github.com/unoplatform/uno/pull/2270

Failing async tests in Uno.UI.RuntimeTests were being incorrectly passed, https://github.com/unoplatform/uno/pull/2301 fixed this
