Download progress reporting can be flakey (ios)

[Thomas101]

Version: 0.10.0

I've been playing with the library and I've noticed that sometimes (maybe 50% of the time) download progress doesn't get reported. This is re-testing with the same url. I've tested on the simulator (ios10) and on an physical iPad (ios9). Here's the code I was using...

RNFetchBlob
    .config({path : dirs.DocumentDir + '/path-to-file.anything'})
    .fetch('GET', 'http://www.example.com/download', {})
    .progress((received, total) => {console.log('progress', received / total)})

After digging through the code I noticed that RNFetchBlob.m makes a call to RNFetchBlobNetwork +enableProgressReport:config:. This call can sometimes happen before RNFetchBlobNetwork -init which means progressTable inside RNFetchBlobNetwork has not been initialized.

Have you thought about using a singleton for the progressTable fields to ensure they're always available? This might help to resolve this issue
