Loads the server-index nodes based on the given range and the initial expand level.

@param {int} iSkip The start index of the loading
@param {int} iTop The number of nodes to be loaded
@param {int} iThreshold The size of the buffer
@param {boolean} bInlineCount Whether the inline count for all pages is requested
@return {Promise<Object>} The promise resolves if the reload finishes successfully, otherwise it's rejected. The promise
						resolves with an object which has the calculated iSkip, iTop and the loaded content under
						property oData. It rejects with the error object which is returned from the server.
