patient_id and patient_name filtering not working on modality pages

[Luuk]

Filtering on patient_id and patient_name results in an error.

Probably due to changing from django 1.8 to 2.2.

Refs #815

Changed custom filters to contain name argument (although not used, it seems obligatory) Changed Charfilter() method functions to be not in single quotes (single quotes seems only applicable if filter functions are defined within the filter class)

manually tested. [skip ci] (no automatic interface testing)

Fixes #815

Thanks Luuk. It has prompted me to look at the name value, which has prompted me to tidy up the CT number of events code...

Refs #815

Changed CharFilter() to have custom filters not in single quotes (seems only applicable if custom filter is defined within filter-class) Changed custom filter functions to also contain the "name" argument (although it is not used in the function)

Tested manually [skip ci] (no automatic interface testing)
