`calc_lifecycle` throws error `WrongDatabase`

[michaelweinold]

When trying to run the calc_lifecycle() method of the pylcaio.Analysis class on a hybridized database based on Ecoinvent 3.5:

analysis_object = pylcaio.Analysis(path_file_hybrid)
analysis_object.calc_lifecycle()

the following error is thrown:

WrongDatabase: Activity database must be hybrid-ecoinvent, but set() was also found

So, when writing the database there is an activity dictionary with the key "database" and the value set(). This is an error at some other point where the database key was set. I wonder if it is the same for all activities?

calc_lifecycle() works fine for a hybridized databased based on Ecoinvent 3.8.
