Ghosted SObject with missing standard type

[pwrightcertinia]

Example

Unknown field or type 'Name' on 'Schema.SObjectType.namespace__customObject__c.Fields'

We have standard fields on GhostSObjectDeclaration including the Name field so it should be finding it, but isn't.

Managed to repro this in GhostPackageTest:

test("Ghost package with custom sobject standard field reference") {
    FileSystemHelper.run(
      Map(
        "sfdx-project.json" ->
          """{
            |"namespace": "pkg",
            |"packageDirectories": [{"path": "pkg"}],
            |"plugins": {"dependencies": [{"namespace": "ghosted"}]}
            |}""".stripMargin,
        "pkg/Dummy.cls" -> "public class Dummy { void func() { String name = Schema.SObjectType.ghosted__myObject__c.Fields.Name; } }"
      )
    ) { root: PathLike =>
      createOrg(root)
      assert(packagedClass("pkg", "Dummy").get.dependencies().isEmpty)
      assert(
        getMessages(
          root.join("pkg").join("Dummy.cls")
        ) == "Missing: line 1 at 49-100: Unknown field or type 'Name' on 'Schema.SObjectType.ghosted__myObject__c.Fields'\n"
      )
    }
  }

It would seem to be because the SchemaSObjectType class has nothing in ghostedSobjectFields / sobjectfields. the main fields are created with type resolver and presumably a "real" sobject type returned by the type resolver would include the standard fields.

Unfortunately the type resolver does not return anything when searching for the ghost object. Can fix this in two places:

• Prevent the error from displaying at all by checking if inputType (the object) is ghosted too - which stops dot expression from doing missing errors on fields of ghosted objects in the specific case.
• Add standard fields to ghostedSobjectfields on SchemaSObjectType so they get picked up only when its a ghosted type.
