v0.7.3 fills up the log with reconnect retries for not availabe devices

[Speedbreaker12]

As mentioned in #186, it's currently not possible to remove old devices from the adapter configuration without manually deleting the object tree. In the past, this wasn’t a major issue, as the adapter would simply log a message indicating that the device was unavailable at startup.

However, with version 0.7.3, the log is constantly filled with reconnect retries for these devices. It would be helpful to either provide an option to remove them from the adapter configuration or revert to the previous behavior. Manually deleting devices from the object tree can be risky for non-beta users.
