3.1.2 breaks on names with dots

[woutermont]

The fix in 3.1.2 (7301c3e) introduces a bug affecting filenames with dots other than the .ts extension, like some codebases use to distinguish between classes extending from certain core interfaces, e.g. my-example.handler.ts. The generator now strips from the first dot, and so goes looking for dist/my-example/index.d.ts instead of dist/my-example.handler.d.ts

We just discovered this bug as well. Exact same issue. +1
