Applets/Audio: Propagate errors by extracting out GUI initialization

Browse source 
This commit extracts out the GUI initialization in AudioWidget into
the new try_initialize_graphical_elements function. This function
is now able to use try_set_main_widget instead of set_main_widget.
It's only called by the fallible try_create method.
