Fix support for 32 bit platforms

Previously running ReTest.jl on 32 bit machines would fail because the `id`
variable would have type Int32 (because it's initialized with a literal) but the
function it was getting passed to (`resolve!()`) expected a Int64.

Also added a 32 bit test to the CI matrix.
