Summary:
When I try to share a home with another user using `HMHome.addUserWithCompletionHandler()`, I get a successful response. But the home never appears on the other user's device when shared from the iCloud account "***".

Sharing does work from other iCloud accounts though - so it seems to be an iCloud issue with the above mentioned account.

I see the following error logs on the device which tries to share the home.

homed[96] <Warning>: Failed to send message with identifier 52727205-CBFB-4A6C-9573-C833CC28E4FF from account: IDSAccount: 0x14e24050 [Service: com.apple.private.alloy.willow  User: ***  ID: EE58EE47-57DC-48F7-8DD5-BE55505420E5  Type: Apple ID  Active: YES  Registration Status: Registered] with error: Error Domain=com.apple.identityservices.error Code=15 "Encryption failed" UserInfo=0x14e1e7a0

Steps to Reproduce:
1. Create a HomeKit home
2. Share the home with another user using `HMHome.addUserWithCompletionHandler()`
3. Accept the invitation on the other user's device
4. Check if the home appears on the other user's device

Expected Results:
The home appears on the other user's device.

Actual Results:
The home does not appear when it is shared from the iCloud account "***".

Version:
8.1.2 (12B440)

Notes:
I have already tried to logout/login from iCloud, change the iCloud security code, restore HomeKit configuration and restart the device with no luck.

The iCloud account "***" is a production account from my father. Please don't wipe or reset the account - he wouldn't be amused. ;)

Configuration:
iPhone 5
