Different demands when re-running the workflow

[irm-codebase]

Re-runs seem to generate different annual demands than those in the pre-builts of the model. Most of these are marginal, but in some cases they can be significant (>10%, so far I only see these in heat and bau_electricity demands).

This generally affects the following:

• space heat
• cooking
• water
• industry specific demands (methane, methanol, diesel, bau_electricity...)

I suspect issue #9 is one of the culprits, at least on the heat side of things. No idea on what is causing industry demands to change.
