Check bootstrapping issue with `quoted.Expr`

Check bootstrapping issue with quoted.Expr.

[nicolasstucki]

The idea is to remove the following pattern to avoid confusion with source file locations

package scala
package quoted {
  ...
}
package internal {
  package quoted {
    ...
  }
}

Is it not rather

package internal {
  package quoted {
    ...

? I am still not sure what happened. Where do classes ... end up when compiled? It should be internal.quoted. Then why does the compiler find the class in internal? Is it the class file or the source file that is to blame? is it the outline parser? It would be good to have a test to verify what goes wrong.
