Exclude failing model from running in CI

[JCGoran]

The model https://github.com/ModelDBRepository/144538 is failing in the CI using NEURON 9 with the following error:

%neuron-executable%: syntax error
 in arm.hoc near line 163
       nqDP.append(1,xo.id,DP,xo.zloc,MTYP.o(xo.zloc).s,shminmlen,shmaxmlen)
                                          ^
        xopen("arm.hoc")
      execute1("{xopen("ar...")
    load_file("arm.hoc")
%neuron-executable%: hoc_Load_file arm.hoc
 in arm.hoc near line 33
 ^
        load_file("arm.hoc")
hoc_run1: caught exception: hoc_execerror: hoc_Load_file arm.hoc

It's not really clear what the source of the problem is, and as the model is quite old, it's probably better to fix it later, but exclude it from the CI in the meantime.

LGTM.

@nrnhines @ramcdougal : FYI. We are excluding this model temporarily. Maybe this error / fix might be obvious to you?
