1. devices: use combined ANY clause for faster cleanup …

   Old device entries for the same user were being removed in individual
   SQL commands, making the batch take way longer than necessary.
   
   This combines the commands into a single one with a IN/ANY clause.
   
   Example of log entry before the change, regularly observed with
   "log_min_duration_statement = 10000" in PostgreSQL's config:
   
       LOG:  duration: 42538.282 ms  statement:
       DELETE FROM device_lists_stream
       WHERE user_id = '@Someone' AND device_id = 'someid1'
       AND stream_id < 123456789
       ;
       DELETE FROM device_lists_stream
       WHERE user_id = '@Someone' AND device_id = 'someid2'
       AND stream_id < 123456789
       ;
       [repeated for each device ID of that user, potentially a lot...]
   
   With the patch applied on my instance for the past couple of days, I
   no longer notice overly long statements of that particular kind.
