Filter update log message prints TUniqueId in non-standard format

Some error messages, such as

Filter update received for non-executing query with id: TUniqueId(hi=-8482965541048796556, lo=3501357296473079808)

print query id as the raw Thrift type rather than our colon-delimited format, e.g. "8a4673c8fbe83a74:309751e900000000". This makes it difficult to trace queries through logs.

Normalize on the colon-delimited format.
