Don't dup schema cache before assigning it
Don't dup schema cache before assigning it

I added this `dup` call in 33fe7cc8892e7e2cf82f7cb0baf467590eb61988 to
avoid sharing the schema cache between the connection and the pool.
Since 49b6b211a922f73d0b083e7e4d2f0a91bd44da90, we no longer assign the
schema cache to the active connection here, so it's no longer necessary.
