renameFile command updates imports with case insensitive paths

[donaldpipowitch]

TypeScript Version: 2.9.2

Search Terms: renameFile, case, import, path, refactor

Code

// file: ./Foo/foo.ts
export const foo = 1;

// file: ./index.ts
import { foo } from './Foo/foo';

• move ./Foo/foo.ts for example into ./test directory

Expected behavior:

./index.ts should be:

import { foo } from './test/Foo/foo';

Actual behavior:

./index.ts is be:

import { foo } from './test/foo/foo'; // lower cased

Related Issues:

I saw #21736 which speaks about a --forceConsistentCasingInFileNames flag as well as a TSServer option useCaseSensitiveFileNames. Not sure if these options can be applied here.

Tested on Mac with case insensitive file system. (Lower cases my imports, breaks CI.)
