This fixes a couple of references to loop variables in parallel tests and deferred functions. When running a parallel test (calling `t.Parallel()`) combined with the table-driven pattern, it's necessary to copy the test case loop variable, otherwise only the last test case is exercised. This is documented in the `testing` package: https://pkg.go.dev/testing#hdr-Subtests_and_Sub_benchmarks `defer` statements that invoke a closure should also not reference a loop variable directly as the referenced value will change in each iteration of the loop. Issues were automatically found with the `loopvarcapture` linter.
