core: ZHA unable to find serial connection after b2 upgrade

The problem

Immediately after the the upgrade to beta 2, zigbee devices that are managed via the ZHA integration work and respond. When you restart core, they fall to come up and are unavailable. A restart of the device does not fix the issue. Downgrading back to beta 1 with or without a restart fixes the issue. While this appears to be a stick issue, the fact that it works after downgrading says otherwise. Have not had an issue until updating to this beta. I’m running HassOS 5.10 64bit on a RPI 4.
