Some analyses no longer work

[romainbh]

Both in Consultation and Edition mode, these following analyses no longer work with QGIS 3.16 (but do with 3.10):

• INVENTAIRES - Pourcentage de résineux
• INVENTAIRES - Volume de la tige moyenne
• INVENTAIRES - Pourcentage PMG
• INVENTAIRES - Répartition des espèces
• INVENTAIRES - Volume par hectare
• COUPES - Volume des coupes par année
• COUPES - Volume des coupes pour une période

I am trying to understand what is going wrong, but this is really not trivial....

Something is going wrong with the addFeatures method, which always returns false since QGIS 3.16 (https://github.com/sitn/SelvansGeo/blob/master/core/thematicanalysis.py#L385)

Maybe we should wait for a minor release to see if this is some kind of QGIS bug.
