[cubejs-client-react] `useCubeQuery` `isLoading` is always true for empty query

[karally]

Describe the bug
isLoading for useCubeQuery is forever true if the query is empty.

To Reproduce

1. Use useCubeQuery to send a query that is empty (empty lists for dimensions, measures, etc)
2. Notice isLoading is always set to true

In the sandbox, notice how it's forever "Loading...". And the console logs isLoading as true too, even though the request finished long ago.

In the code:

The default value for isLoading on L12 is the same as the opposite of the skip option. Then the isQueryPresent check for empty query skips everything else so isLoading is never updated again.

Expected behavior
isLoading should be false as soon as the request finishes/never been fired, whether the query was empty or not.
