Don't offer to change spelling to not-yet-defined variables

**TypeScript Version:** 2.8.1 **Search Terms:** suggest change spelling auto fix import **Code** ```typescript // This import is missing, but can be auto-suggested import { /* SomeClass */ } from "./SomeClass"; const bindContainer = (container) => { const someClass = container.get(SomeClass); }; ``` **Expected behavior:** When I ask for auto-fixes on the `SomeClass`, it should only suggest to add it to the import declaration. **Actual behavior:** Two suggestions are given: * `Change spelling to 'someClass'` * `Add 'SomeClass' to existing import declaration from "./SomeClass"` We can statically reject the rename suggestion here because this is in the initializer of the variable.
