tslib@1.12.0 breaks typeorm

After upgrading tslib to 1.12, I get the following error message when requiring ‘typeorm’(which requiring tslib@^1.9.0)

> require('typeorm')
Uncaught:
TypeError: Cannot set property EntityManager of #<Object> which has only a getter
    at Object.<anonymous> (/path/to/typeorm-test/node_modules/typeorm/index.js:120:23)

It seems like there’s breaking changes in tslib.__exportStar() that defining getter instead of defining properties on target object. Resulting that once a symbol has already been exported by export * from './other-files' indirectly, the above error will be thrown when it is explicitly exported again in same file.

P.S. If you have solved the problem. please close the issue that you opened here.

I’ve solved it before submit this issue, but I think it’s an accidential breaking change of tslib and they should fix it.
