Update RNFetchBlob.m

nadav2051 · web-flow · commit deb3588a3662 · 2019-08-28T11:32:58.000+03:00
Solved an issue where the rootNavigationController is not necessarily the currently displayed controller, which caused an error of:
Warning: Attempt to present &lt;SecondViewController: 0x7fb54b523240&gt; on &lt;ViewController: 0x7fb54b61e7f0&gt; whose view is not in the window hierarchy!
