finalize function not generated or mocked

[shavinda]

Just be aware about usual MockK support pattern.
Tickets are checked from time to time, replied, discussed, labeled, e.t.c.
But real fixes are applied in a month-two month period in a bunch.
If you think this is unacceptable, go on, join the project, change the world.

Please remove sections wisely

Below information is actually needed to make all the process of fixing faster.
Choose main points. Don't blindly follow this as a set of rules.
Don't waste much time. Usually, the main thing is to have a good reproducible minimal code.

Prerequisites

Please answer the following questions for yourself before submitting an issue.

• I am running the latest version
• I checked the documentation and found no answer
• I checked to make sure that this issue has not already been filed

Expected Behavior

Please describe the behavior you are expecting
The finalize function of an interface should be mocked / generated the same as any other function.

interface MyMockkTest1 {
    fun doSomething()

    fun finalize() // Not mocked
}
interface MyMockkTest2 {
    fun doSomething()

    fun finalize() : Boolean  // Not mocked
}
interface MyMockkTest3 {
    fun doSomething()

    fun finalize(value: Int) : Boolean  // Mocked and works as expected
}

Current Behavior

What is the current behavior?
Method that are named finalize (whether it returns Unit or any other value), is not mocked as expected.
When a test invokes the mocked function or attempting to verify it an error is producing

`Receiver class MyMockkTest2$Subclass6 does not define or inherit an implementation of the resolved method 'abstract boolean finalize()' of interface MyMockkTest2.
