Fix fill missing in industry sector ratios intermediate

[tgi-climact]

Changes proposed in this Pull Request

I found a strange behaviour of build_industry_sector_ratios_intermediate. When looking to intermediate steps between current and futur industry, missing values were wrongly filled with futur data.

I suggest to use futur data only when we miss the full description of the technology (carrier whise).

Here is an example of Ammonia in Belgium where we see a mix of current and futur data.
