Summary:
Before https://github.com/yugabyte/yugabyte-db/commit/3aa0773f89e47d5fdf341860241913988f7b54fd the first trace size included the tracing output created due to the CREATE TABLE command as well.  Although the expected trace size was updated, the actual trace logged is even smaller when using shared memory.

Fix:
- Update trace size to be more conservative
- Provide custom naming function for the test
