sqlite3_test.go: Move Go 1.13 test to sqlite3_go113_test.go (#883)

Commit 4f7abea96e added a test that uses Conn.Raw, which was added in
Go >= 1.13. The go-sqlite3 project runs tests with Go >= 1.11. Remove
the test from sqlite3_test.go, so it only runs with the correct
versions of Go.

Instead of adding a new test, modify the existing test that already
uses Conn.Raw() to check the type of driverConn.
