bridge DB changes BridgeDistribution method for an already established relay

I removed yesterday the line

BridgeDistribution email

from torrc of https://metrics.torproject.org/rs.html#details/8311FFDEFB310BD65393D0B21EB8D0F0A867BB9E:

root@uhu:~# ls -l /etc/tor/torrc 
-rw-r--r-- 1 root root 462 Apr 28 17:28 /etc/tor/torrc

and realized now that the "Bridge distribution mechanism" changed to "settings".
