#5630) Corrects thin ice/snow treatment of enthalpy and other tracers This fix redistributes enthalpy and other tracers evenly in snow and ice when their respective thicknesses are < 1e-15 . Previously, these tracers were zero'd non-conservatively. Also corrects a bug in the zeroing of snow thicknesses, and removes snow in thickness_changes if the ice vanishes. Fixes #5124 [non-BFB]

See issue #5072: "MPAS-SI crashes when running in thermodynamic mode (F cases) with small time steps."
When dtime=1, as used in the time step convergence (TSC) test, an issue occurs with MPAS-SI at a particular time step.
It seems to depend on input data, as for different initial atmosphere / land conditions causes the problem to appear at different time steps (#5072 (comment)).
