Size check can be replaced with 'isNotEmpty()'

Reports size checks of Collections/Array/String that should be replaced with isNotEmpty().

Using isNotEmpty() makes your code simpler.

The quick-fix replaces the size check with isNotEmpty().

Example:

  fun foo() {
      val arrayOf = arrayOf(1, 2, 3)
      arrayOf.size > 0
  }

After the quick-fix is applied:

  fun foo() {
      val arrayOf = arrayOf(1, 2, 3)
      arrayOf.isNotEmpty()
  }
