minification error

[azu]

When use Almin with minification like UglifyJs, always throw error.

assert.js:113Uncaught AssertionError: "t" is duplicated in the `new StoreGroup(stores)`.
You should check each Store class name.

class t extends Store { ... }
      ^
      store.name

It is caused by minification, it make store name to t.

Workaround

use unassert.
