Public project type does not appear in dropdown

[MontrealSergiy]

The project groups/category in drop-downs are sometimes different from project types shown say in tables. For example, there is no Public category in drop down, yet some projects are shows as of Public type elsewhere. Note the filters dropdown code is different from groupped project categories e.g. it a task project dropdown. See a snapshot below (for filter)

Note that filter dropdown is different from task project categories.

dropping a premature return in pretty names method or more carefully handling public and such into preparatory part will fix the categorized list (but not filter) ( see an attempted solution admingroup PR )
