new.target not supported by Safari, IE, and Edge

[rmhrisk]

It seems we use new.target, according to: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/new.target

It is not supported by Safari, Edge, IE:

We are experiencing an error currently errors in workers as well as with UglifyJS on on IE, as is expected as a result.

I would have assumed the transpile would have moved to:

this.constructor.name === "ClassName"

For this but it seemed not to.

This bug is to track this issue.

Seems there is no elegant way how to replace the "new.target". Thus I decided to just remove it - in fact the "new.target" needs only for additional "smart protection" from making abstract class and nothing else. So, it could be removed without any "side effects".

Solved in latest release.
