Call chain on collection type can be simplified

Reports two-call chains replaceable by a single call.

It can help you to avoid redundant code execution.

The quick-fix replaces the call chain with a single call.

Example:

  fun main() {
      listOf(1, 2, 3).filter { it > 1 }.count()
  }

After the quick-fix is applied:

  fun main() {
      listOf(1, 2, 3).count { it > 1 }
  }
