Migrate changed unique_ids where it is possible.

Some changes in this version are still unhandled:

ETOP FCU: child lock changed from switch to lock, to match other devices
Holman WX1/2: "Time left" changed from number to sensor
Proscenic M9: Error message changed from sensor to a problem binary_sensor
Rotenso Ronix and Stadler Form Roger: unnamed sensor given PM2.5 class
   (corrects a mistake from previous migration)
Shinco 30D: removes the fault code sensor (moved to an attribute on
   the problem binary_sensor, like other devices)
Vacplus: Fault sensor changed to binary_sensors for general problem
   and tank full
Garza irrigation: alarm binary_sensor changed to problem
   binary_sensor, but cannot be migrated as other legitimate
   binary_sensors for actual alarms are still labelled "alarm"
