DataView of an Empty Module throws java.lang.IndexOutOfBoundsException

The following errors as it tries to get the `lastId` for an empty module (which allocated no ids?). I would expect to get a "view is non-total" error:

```scala
//> using scala "2.13.10"
//> using repository "https://s01.oss.sonatype.org/content/repositories/snapshots"
//> using lib "org.chipsalliance::chisel::5.0.0-M2"
//> using plugin "org.chipsalliance:::chisel-plugin::5.0.0-M2"
//> using options "-Ymacro-annotations"

import chisel3._
import chisel3.experimental.dataview._
import circt.stage.ChiselStage

class Bar extends RawModule

class Baz extends Bundle {
val a = Bool()
}

class Foo extends Module {

private val bar = Module(new Bar)
private val baz = Wire(new Baz)

private implicit val view = PartialDataView[Bar, Baz](
_ => new Baz
)

baz := bar.viewAs[Baz]

}

object Main extends App {
println(
ChiselStage.emitSystemVerilog(
gen = new Foo,
firtoolOpts = Array("-disable-all-randomization", "-strip-debug-info")
)
)
}
```

This produces:

```
