typeError when copy-pasting exchanges between activities

[simb-sdu]

I am working on inter-activity copy/pasting of exchanges

The pasting currently only pastes the exchange without any field values (e.g. value, comment, formula, uncertainty)

I am starting to implement just the value, formula, and comment, which seems to be the exchange_modified() signal (defined as modify_exchange(exchange, field, value) in \controllers\activity.py) Having some trouble to get this function working, probably because of wrong data types. feeling stuck, see comments in code

see commit on my fork
