MDL-36223 Assign: User outline report grade display

Use str_long_grade for user outline report because it handles scales and
no grade.

Thanks to Jean-Daniel Descoteaux for suggesting this fix.
MDL-38487 qtype match restore: problem with blank ids.

MDL-39445 get_plugin_list clean_param use is slow

get_plugin_list was calling clean_param($pluginname, PARAM_PLUGIN) a

A specific function for this case, (which we then also use from
clean_param) is a performance win.

This makes it easier for teachers editing questions.
MDL-31193 display the correct and translated token valid until date
MDL-39491 Fix order of Workshop submission text processing

important to make filters work correctly.
