Fixed resources import

[Marishka17]

Motivation and context

Fixed:

• wrong location of tmp file when importing job annotations

•   File "/home/maya/Documents/cvat/.env/lib/python3.8/site-packages/rq/worker.py", line 795, in work
      self.execute_job(job, queue)
    File "/home/maya/Documents/cvat/cvat/rqworker.py", line 37, in execute_job
      return self.perform_job(*args, **kwargs)
    File "/home/maya/Documents/cvat/.env/lib/python3.8/site-packages/rq/worker.py", line 1389, in perform_job
      self.handle_exception(job, *exc_info)
    File "/home/maya/Documents/cvat/.env/lib/python3.8/site-packages/rq/worker.py", line 1438, in handle_exception
      fallthrough = handler(job, *exc_info)
    File "/home/maya/Documents/cvat/cvat/apps/engine/views.py", line 2233, in rq_exception_handler
      rq_job.exc_info = "".join(
  AttributeError: can't set attribute
  

Resolves #5773
Resolves #5563

• root causes of the issues:
  • the annotation file was uploaded to the server by tus protocol and rq job was created but no one next requests for checking status were not made. (e.g. user closed the browser tab)
  • the annotation file was uploaded to the server by tus protocol but rq job has not yet been created (e.g cvat instance restarted)
  • tasks/projects creation from backups with the same name at the same time by different users

How has this been tested?

Manually

@Marishka17, AFAIK, the problem is also actual for interrupted backup uploads.

@zhiltsov-max, Yes, I know, this PR should fix that too.

Probably, it makes sense to reduce the delay down to a couple of seconds. We totally don't want unit tests running more than a minute, unless they are in a special test suite.
