While working on the auto-join communities feature, I discovered an issue where the `commCommunityID` in the blob payload did not have the keyserverID:
```
farcasterChannelTagBlobs [
{
"commCommunityID": "83887",
"farcasterChannelID": "comm"
},
{
"commCommunityID": "145350",
"farcasterChannelID": "memes"
},
{
"commCommunityID": "83887",
"farcasterChannelID": "farcaster"
},
{
"commCommunityID": "83885",
"farcasterChannelID": "founders"
}
]
```
However, the the thread ids in the `threadInfos` look like this: `256|83843`, where the keyserver id is appended to the front of the thread id and the two ids are separated by a pipe character. This diff updates the value of `commCommunityID` to follow this convention
