PinskyRinzel sisat fix

[JustasB]

Addresses OpenSourceBrain/PinskyRinzelModel#7 with solution from LEMS/jLEMS#88 (comment)

Without this fix, the abstract cells example fails to compile in NEURON:

Thanks @JustasB. Looking into this here: https://github.com/NeuroML/NeuroML2/tree/test_pinrinz

@JustasB did you check this implemetation by running this example in Neuron: https://github.com/NeuroML/NeuroML2/blob/development/LEMSexamples/LEMS_NML2_Ex22_PinskyRinzelCA3.xml?

The mod file compiles, but the simulation fails...

@pgleeson I was able to run the example LEMS in Neuron with a dt of 0.0001 or with CVODE on. I'm attaching the full LEMS file I used. I reduced the simtime to 250ms from 1.5s to keep the .dat file size reasonable.

Take a look,
