Michael Jones f82552638c Improve keyMirror types & tests (#13738) ...

Using mapped types from Typescript 2.1.

The type returned is as we might expect from keyMirror. In the test case
of:

  keyMirror({key1: null, key2: null})

We get the type:

  { key1: 'key1'; key2: 'key2'; }

Instead of:

  { [key: string]: string; }

Which is what we got before.

Both check lines in the test file fail with the previous type
definition.
