Php schema patch to update channel id's of past events.

Summary: Php schema patch to update channel id's of past events.

Test Plan: Having some proxy issues here due to which connection is timing out and bot is not able to log into IRC. Bot connects to IRC in my home though ! So I wasn't able to quite to test this by running storage upgrade.
