mosaicService.mosaicsAmountViewFromAddress only returns one mosaic

[dgarcia360]

1. Expected behavior and actual behavior.

mosaicService.mosaicsAmountViewFromAddress only returns one MosaicAmountView object although it should return all of them.

2. Steps to reproduce the problem.

The following snippet only logs one random MosaicAmountView corresponding to a mosaic owned by the user (not always the same).

 const mosaicService = new MosaicService(accountHttp, mosaicHttp);
 mosaicService.mosaicsAmountViewFromAddress(address).subscribe(x => console.log(x));

To get the full mosaics balance from an account, the dev has to manually pipe the object and transform the response to an array as follows.

 const mosaicService = new MosaicService(accountHttp, mosaicHttp);
 mosaicService.mosaicsAmountViewFromAddress(address)..pipe(mergeMap((_) => _).toArray()).subscribe(x => console.log(x));

3. Specifications like the version of the project, operating system, or hardware.
