core: Homekit not working on ios 12

Home Assistant release with the issue: 0.100.3

Last working Home Assistant release (if known): ~0.97 (before ios 13 release/upgrade)

Operating environment (Hass.io/Docker/Windows/etc.): Hass.io running on NUC ubuntu

Integration: Homekit

Description of problem: Homekit stopped working once I upgraded my iphone to ios 13, my other device (ipad) is ios 12.4.1 (can’t be upgraded to 13). At first it became some buggy when ios 13 started combining/grouping switches that probably wasn’t supported in ios 12. I removed all homekit related integration, deleted .homekit.storage, removed pairing from home app (automaticly removed from all devices), signed out icloud (also factory resetted ipad), restarted router, restarted hass (repeated several times). on ios 12 I can’t pair at all, it says Can’t add homeassistant bridge. on ios 13 it works as expected. once it added in ios 13 it synced via icloud and i can see the entities on ipad (ios 12) as well, but all of them with no response. Tried adding ip address and safe mode. Tried to get some answer in community forum: https://community.home-assistant.io/t/homekit-works-only-ios-13

Problem-relevant configuration.yaml entries and (fill out even if it seems unimportant):

ip_address: 10.0.1.201
