[iOS] Spotify_sdk player's requests NEVER come back with their callbacks.

Is this a native Spotify SDK issue
No

Are you using a Free or Premium Spotify account
Premium

Expected behavior
Spotify_sdk must respond with a callback when I perform actions like play/pause/getPlayerState on a song.

Describe the bug
Pre-issue:
I was facing an issue like this and I try to solve his way but it didn't solve. I also tried with this way around where I added a wrong spotifyUri while connecting using SpotifySdk.connectToSpotifyRemote() and it worked!! i.e., Spotify app didn't played song automatically after adding wrong spotifyUri.

Actual/current issue:
When I perform actions like play/pause/getPlayerState on a song, my requests go but they NEVER come back with their callbacks after few successful requests. Rather my all queued requests respond back suddenly when I switch from the app to Spotify App. See the screen shot below:

Steps to Reproduce
Steps to reproduce the behavior:

1. Followed iOS quick start documentation
2. Connect to Spotify remote with/without accessToken but with a wrong spotifyUri as a param
3. Play and keep playing different songs one by one
4. After few successful attempts, you won't be able to perform further actions on a song

@fotiDim - Can you please check my query? It'd be much helpful to meet my deadline.

@irfan-429 some clarifications needed:

• Does the issue also happen when you pass a valid spotifyUri?
• Does the issue also happen when you don't pass any spotifyUri?
• "After few successful attempts, you won't be able to perform further actions on a song" Does that literally mean that you cannot perform any action (eg. pause) or just that you are not getting back the callback?

Also how are you sure that this is not a native Spotify SDK issue?
