* fix: 5693 - able to run tasks without minimum duration wait
Impacted files:
* `background_task_manager.dart`: made it possible to force an immediate run if possible
* `offline_tasks_page.dart`: force an immediate run if possible when clicking on the refresh button
* Added a call to BackgroundTaskManager.run related to prices
* Minor fix
* Wtf tests
* Ugly fix for mocking hive
