Fix export job dataset

[Marishka17]

Motivation and context

In the previous implementation, the annotation file for the job contained information related to the task. Zip archive with the dataset contained all images of the task. This PR fixed this issue.

How has this been tested?

Manually

When I tried to export the 2nd job in a task with 6 images and 3 jobs (2 img each) as Segmentation mask 1.1, I've got the following error:

Traceback (most recent call last):

    self._result = self._execute()

  File "/cvat/apps/dataset_manager/formats/utils.py", line 53, in make_colormap
    labels = [label for _, label in instance_data.meta[instance_name]['labels']]
KeyError: 'task'

This also applies to other segmentation formats (CamVid, Cityscapes). CVAT for images and COCO seem to work.

Also, don't you think the old button for task export in the menu of the annotation page should be restored? Users may expect it to be there, and it was quite useful there.

Also, consider adding a job menu button here:

Thanks, this issue has been fixed

I guess that button to export task should be on the task detail page or on the tasks page. Let's wait for customer requests.

Also, consider adding a job menu button here:

We have a button to export jobs in the annotation view and on jobs page. Let's wait for customer requests.
