Generics defaulting doesn't work

[wassy92x]

Subject of the issue

If we like to create an object of an interface with a generic default, the property can't be accessed.
Workaround is possible by using createMock<A<string, string>>

Your environment

• ts-auto-mock version: 3.1 (master - branch)
• typescript version: 4.1.3
• node version: v14.15.1
• npm version: v14.15.1

Steps to reproduce

For example:

interface A<T, E = T> {
  a: T;
  b: E;
}

const myMock: A<string> = createMock<A<string>>();
console.log(myMock.b);

Expected behavior

'b' should be defined and should be of the first passed type. In the example it should be an empty string

Actual behavior

As soon as I try to access 'b', there is an error: "ReferenceError: t is not defined"

Oops, we'll try to figure out why that fails, thanks for opening the issue!
