This commit fixes a PostgresException error that occurred when
processing timeline activities with empty workspaceMemberId values.
workspaceMemberId appears to be optional but we set it to an empty
string when it is not present. This subsequently causes issues in the
postgres query.
This change fixes the root cause. Empty string handling is added to the
postgres query also for situations where bad data has already entered
the db
