update _modelchain_ac_model for multi array inverters

[wholmgren]

pvlib/pvlib-python#1147 and pvlib/pvlib-python#1150 changed the object oriented api for the new multi-array inverter functions. Now you just pass "sandia" or "pvwatts" and the objects determine which function they should call. So SPI needs to update PVWattsInverterParameters._modelchain_ac_model and SandiaInverterParameters._modelchain_ac_model. The change is available in v0.9.0-alpha.2

We'll need to wait for pvlib/pvlib-python#1157 otherwise we'll have to adjust the logic below to not return a list if num_arrays == 1

Merged that PR. Do you want an alpha-3 now?

I think there is still the issue raised in #119. I'll try and track it down and raise in pvlib
