[#60826048] Style change: .count() to .count
[#60826048] Imports can't be edited if they have finished
[#60826048] Add fixture_path to test import with a real zip.
[#60826048] Import was processing import_file each time Import was updated,
beacuse of that duplicate import modules where created.
The first solution was to call process_import_file after_create instead of
after_save but the app sets the import_file *after* creation so i added
a method already_processed?
