Bug Report

Connecting device from IAP-BT to IAP-USB causes manager to stop registering to HU

Reproduction Steps

Ensure you have SDL enabled App on Phone.
Pair and connect iPhone over BT to Sync 3.2v2
App should register on SYNC
Now, connect the same device via USB to SYNC
(Internally, when the device connects over USB the device and SYNC setups another iAP session over USB. Once SYNC can determine that it is the same device which is connected over BT and USB, SYNC will proceed to disconnect the iAP session over BT)
Note the messages received on App (SDL disconnects, doesn't appear on head unit)

Expected Behavior

App should un-register since they were connected over BT and then immediately re-register over USB

Observed Behavior

App unregisters and then disconnects the manager completely over USB

OS & Version Information

• iOS Version: iOS 11, iOS 12
• SDL iOS Version: 6.0.1
• Testing Against: SYNC 3.2v2

@SatbirTanda See if this PR (released in v6.1.2) fixes your issue #1114

Hey Joel - after testing with 6.1.2 it looks like the issue persists - I've attached a log in the original post

[NicoleYarroch]

I was able to reproduce on iOS 12.12 (iPhone XS Max) and SDL_iOS 6.1. I suspect the issue is occurring because the stream delegates for the EAAccessory are not being set to nil when the EAAccessory disconnects. I will create a PR to fix this issue.
