Fix Shelly RPC RSSI sensor removal

[thecode]

Proposed change

#108390 removes the RPC (Shelly Gen2) RSSI sensor if the first WiFi station is disabled, Shelly Plus/Pro devices supports two WiFi connections and it is possible to enable the second one and disable the first one (I am using this as normal testing to cause a device to connect to a far AP).

Pulling this from the milestone, as it causes build issues (as it relies on other changes not in the current stable release for the tests).

Will be part of 2024.3 instead.
