Fix totalconnect config flow

[austinmroczek]

Proposed change

This fixes the bug preventing new TotalConnect integrations being created from the configuration flow.

I forgot to account for an upstream change that used synchronous IO in a new spot, and it was hidden by the way I'm using Mock in tests.
