Fix typo in logger output for source model info
The logger prints out
frequency_domain_source_model: None
frequency_domain_source_model: __main__.NRHybSur3dq8
parameter_conversion: bilby.gw.conversion.convert_to_lal_binary_black_hole_parameters
where the second line should say
time_domain_source_model: __main__.NRHybSur3dq8
