Error when running pde_solver_test() with all glaciers

[facusapienza21]

The test pde_solve_test,

@testset "PDE solving integration tests" pde_solve_test(; rtol=0.01, atol=0.01, save_refs=false, MB=false, fast=true)

fails when fast=false. This just runs the test with a larger list of glaciers, but there is some of them with missing data that make the test fail.

    if fast
        rgi_ids = ["RGI60-11.03638", "RGI60-11.01450", "RGI60-08.00213", "RGI60-04.04351", "RGI60-01.02170"]
    else
        rgi_ids = ["RGI60-11.03638", "RGI60-11.01450", "RGI60-08.00213", "RGI60-04.04351", "RGI60-01.02170",
        "RGI60-02.05098", "RGI60-01.01104", "RGI60-01.09162", "RGI60-01.00570", "RGI60-04.07051",                	
        "RGI60-07.00274", "RGI60-07.01323",  "RGI60-01.17316"]
    end

It will be good idea to omit those or fix the problem in some other way.
