Would only have subjective nits, looks good to me overall!

The code you've got right now LGTM.

One thing that I would ask is could you please make it ignore the generic.
Unless I'm mistaken, if I do something like:

options = {
    'React.Component': { .... }
}

against this code:

class Foo extends React.Component<Props> {}

Then it will not detect it because getText will include the generic.
(If I'm wrong, then just add a test for that case, and we're good to go!)

Turned out it works fine with generics. I have added the tests. In short it works because TSTypeReference.typeName does not includes the type parameters parts.
