comms/py-fritzconnection: update to 1.12.2

Changes since last ports version 1.12.0:

• FritzCall: New method hangup(). (#184)

• FritzHosts: bugfix: removed issues preventing the method get_hosts_attributes() to return a list of dictionaries representing the host-attributes. (#190)

• bugfix in 'setup.py`: add long_description_content_type="text/markdown", because it is not used as default.
