title: Lint considers Kotlin MutableMap.forEach() as java.util.Map.forEach()
body: <p>I am using Kotlin's MutableMap in my Android project. And trying to do some action per item. So here is my code.</p>
  
  <pre><code>private val uris: MutableMap&lt;String, Uri&gt; = mutableMapOf()
  // ... Fill the items here ...
  uris.forEach {
      val ref = FirebaseFirestore.getInstanse().reference
      uploadFile(ref, it.value)
  }
  </code></pre>
  
  <p>Everything just works fine at runtime, but my CI build fails with below lint error:</p>
  
  <pre><code>MyActivity.kt:142: Error: Call requires API level 24 (current min is 16): java.util.Map#forEach [NewApi]
                uris.forEach {
                     ~~~~~~~
  </code></pre>
  
  <p>I know we can't use JDK-8's Map for Android projects until the min sdk is 24. But why lint is considering it as JDK-8's Map?</p>
  
  <p>For further information I tried getting the Java code from Kotlin Bytecode option in AS and found that forEach is replaced with while loop and iterator as expected.</p>
  
  <p>So what could be reason and how to solve this? Any lead will be appreciated.</p>
