Prevent name clashes between a function in class and a function call in current scope.

[ivk1800]

This pull request aims to fix clashes name between a function in class and a function call. We have below generate code, which contains function in class and call another function with same name.

Actual:

      package com.squareup.tacos
      
      import com.squareup.Fridge.meat
      
      public class DeliciousTaco {
        public fun build(): Taco = Taco(deliciousMeat = meat { })
      
        public fun deliciousMeat() {
        }
      }
      
      public class TastelessTaco {
        public fun build(): Taco = Taco(meat = meat { }) // <----
      
        public fun meat() { // <----
        }
      }
      

Expected:

      package com.squareup.tacos
      
      import com.squareup.Fridge.meat
      
      public class DeliciousTaco {
        public fun build(): Taco = Taco(deliciousMeat = meat { })
      
        public fun deliciousMeat() {
        }
      }
      
      public class TastelessTaco {
        public fun build(): Taco = Taco(meat = com.squareup.Fridge.meat { }) // <----
      
        public fun meat() { // <----
        }
      }
