remove various warnings issued by Spawn

Simulating Buildings.ThermalZones.EnergyPlus.Validation.Schedule.EquipmentSchedule in Dymola leads to the warnings below.
This issue is to remove them.

The output is from 753a530 (the current master).

@kbenne : With Spawn-0.1.0-3ec0a1fa6e-Linux.tar.gz, the warning about the humidity is still there:

Is this checked and passes on your CI test?

[kbenne]

The model I was testing didn't show that one. I think it was the small office reference building that I was using in Chicago. Anyway, I'll see what I can do. This one might not be addressed by release. I do not have automated tests to capture the warning count so CI is blissfully unaware.

[mwetter]

This will be corrected after Buildings 8.0.0 release.

This is still an open issue, and now there is another warning about the W/person. The log is

0.000 EquipmentSchedule.building: Warning from EnergyPlus: fall outside typical range [70,1000] W/person for Thermal Comfort Reporting.

@mwetter I've fixed two reoccurring warnings.

1. Invalid people activity value
2. Out of range humidity values

I've been specifically using the Buildings.ThermalZones.EnergyPlus.Examples.SingleFamilyHouse.AirHeating model as a test case, but if you know of other models that are generating different warnings the let me know. I think this clears up the common warnings that we are seeing.

Note that item 2 is significant beyond simply fixing a warning. The warning was a symptom of the underlying problem that I was not updating the moisture balance correctly.
