Redundant 'if' statement

Reports if statements which can be simplified to a single statement.

Example:

  fun test(): Boolean {
      if (foo()) {
         return true
      } else {
         return false
      }
  }

After the quick-fix is applied:

  fun test(): Boolean {
      return foo()
  }
