The task object priority is servering asl  'dummy' for  normal tasks.

Related taskwrapper object should be updated as well,
since the 'real' priority scheduling is done using the
Taskwrapper object.

Fixes: #989

Production is using mysql:8.0

Fix update priority on task does not apply to taskwrapper

Reenabling skipped tests

Usefull when developing feature which require large sets.
Like pagination and expansion.

Instead of fetching the related object one object at the time,
requested all related objects ,via fetchExpandObjects, for given list
of objects.

This will reduce DB queries required for expansion from
O(<num-objects> * <num-expands>) to O(<num-expands>)

Added bonus we do not fetch duplicated objects anymore,
 reducing the amount of objects which requires processing.

Fixes #1017

implemented exportCrackedHashes helper on new API

…n int which causes issues with the new API not sending an int where an int is expected.

as the autoincremented IDs in MySQL always will be of type int, we cast it after retrieving

added tests to test different import scenarios

… left lists for hashlists

added tests for both helper actions

hashlist helpers implemented

#1044)
