Recompiling a ts file after changing the case of the filenames does not propogate the case change

Howdy,

I have a file called "Example.ts", I compile it, then I rename it to "example.ts" and re-compile.

The javascript files that get output remain "Example.js".

I expect my rename to propagate to my .js files.

The bug can get particularly ugly in visual studio, here is an example video:

Here is my tsc:

{
  "compilerOptions": {
  "noImplicitAny": false,
  "noEmitOnError": true,
  "removeComments": false,
  "sourceMap": true,
  "target": "es6"
},
  "exclude": [
    "node_modules",
    "wwwroot"
  ]
}

am using tsc 1.6.2
