Bundler repeat importing issue

[ije]

here is my entry.ts

import Head  from "https://deno.land/x/aleph/head.ts"
import * as Head2 from "https://deno.land/x/aleph/head.ts"
console.log(Head, Head2)

when i run deno bundle entry.ts bundle.js, i got an error:

thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', /Users/runner/.cargo/registry/src/github.com-1ecc6299db9ec823/swc_bundler-0.17.1/src/bundler/chunk/merge.rs:128:22
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

in deno 1.5.4 (bc79d55, release, x86_64-apple-darwin)

Just tested on latest master, it's still panicking though it's a different error:

thread 'main' panicked at 'assertion failed: `(left != right)`
  left: `[]`,
 right: `[]`: forced_ns should be modified only if a namespace import specifier exist', /Users/biwanczuk/.cargo/registry/src/github.com-1ecc6299db9ec823/swc_bundler-0.17.1/src/bundler/import/mod.rs:315:21

@kdy1 could you take a look?

Of course, I'll fix it asap.
