Add boolean field for Adaptation Project into $StudyInfo

[patrickkaleta]

Since we want to remove the Study variant fieldfrom the Study Scenario object, we need to add it separately to the $studyInfo object, so that the Map and Table components can query and filter data for the baseline and for the adapted scenario.
Boolean field has_adapted_scenario will be set based on whether or not the Study contains an "Adaptation Project" Group node.

In the process the study_variant attribute will be removed from the study_scenarios and study_presets of the $studyInfo object.

FYI: @p-a-s-c-a-l and @therter
This is now available on DEV for further testing. study_variant is now gone from the study_scenarios and study_presets and instead has its own boolean field called has_adapted_scenario inside the $studyInfo object.
