Autogenerated Kotlin getters/setters shouldn't be tested

[volivan239]

Description

For each field Kotlin automatically generates getter/setter, there is no sense in testing them. However, they are shown in member list after launching action.

To Reproduce

Declare simple Kotlin class like class B(val x: Int), launch action on it.

Expected behavior

Action is disabled as class has no testable methods.

Actual behavior

Action is enabled, members list has one method getX(), after selecting and launching generate we receive error No methods found.
