Fix potential reflection warnings from use of next.jdbc.prepare/statement

CHANGELOG.md

@@ -5,6 +5,7 @@ Only accretive/fixative changes will be made from now on.
 Changes made on master since 1.0.462:
 * Add tests for `"jtds"` database driver (against MS SQL Server), making it officially supported.
 * Switch from OpenTable Embedded PostgreSQL to Zonky's version, so that testing can move forward from PostgreSQL 10.11 to 12.2.0.
+* Fix potential reflection warnings caused by `next.jdbc.prepare/statement` being incorrectly type-hinted.
 * Address #119 by clarifying realization actions in the docstrings for `row-number`, `column-names`, and `metadata`.
 * Address #115 by adding equivalent of `db-do-commands` in the `clojure.java.jdbc` migration guide.
 * Add log4j2 as a test dependency so that I have better control over logging (which makes debugging easier!).
