v2.11.0 — nine faults from an independent review fixed

Nine faults found by an independent review, all fixed. None of them was causing trouble in my house, but each would have caught somebody out.

• Separate devices now work. Splitting a reading out into a device of its own stopped the original device updating. The original now keeps its messages and passes the reading on, and switching the new device off or deleting it no longer cuts the original off.
• A smoke alarm that also measures temperature is made as an alarm, so its on and off follows the alarm. One made as a temperature sensor by an older version writes an error to the log each time it reports smoke, saying how to make it again.
• Refresh Device List from MQTT works. It now asks the MQTT broker for the list zigbee2mqtt left there, and says so in the log if none arrives.
• Device Settings that belong to a group, such as a bulb's colour options, now reach the device inside their group.
• A failed firmware update fires the Firmware Update Failed trigger once, not twice, and a firmware check says whether an update is waiting.
• A device renamed in zigbee2mqtt can no longer undo Refresh Device Capabilities if both happen at once.
• Motion cannot clear by mistake after a restart on a sensor with both a motion detector and a presence radar.
• Topic Prefix can have several levels, such as house/zigbee2mqtt. A prefix with + or #, or one inside the other, is refused.
• The first device on a brand new Zigbee network is made by itself, even if it joined while the plugin was not connected.
