Fix disappearing swipeRef circle before data set

[mohaxspb]

We can fix it by greater interval of checking it (to 5s from 3) or by adding DB tasks to list in service...

I vote for 1st option)))

We can replace List by List with urls of loading category, which we can remove from list after getting final message from service;

And we do not need to store page in this case, because we must not be able to start loading something if we are do it at this moment;
