Misleading error when comparing resutls

When running a test if the test fails, it will stay that 'Array' did not equal 'List'. While the important part is that the elements do not match.
To reproduce the issue please run the following test

```
import org.scalatest.{FlatSpec, Matchers}
import com.holdenkarau.spark.testing.StreamingSuiteBase
import org.apache.spark.streaming.dstream.DStream

object TestFunctions {

def doSomeOperation(input: DStream[String]): DStream[String] = input.map { i =>
i + "x"
}
}

class MisleadingErrorTest extends FlatSpec with Matchers with StreamingSuiteBase {

"DoSomeOperation" should "map String values to a well format string" in {

val input = List(List("{ \"userId\": 1}"))

val expectedL = List(List("{ \"userId\": 1}"))

testOperation(input, TestFunctions.doSomeOperation, expectedL)
}
}
```

This produce the following error
`[info] - should map String values to a well format string *** FAILED ***
[info] Array("{ "userId": 1}x") did not equal List("{ "userId": 1}") (StreamingSuiteBase.scala:105)
`

The message should say List(...) did not match List(...) or Array(...) did not match Array.

Start at StreamingSuiteBase.scala:105, where the reported comparison error is produced, and reproduce it with the MisleadingErrorTest example from the issue. Check how the compared values are represented in the failure message. Done means the message reports matching collection types, such as List(...) did not match List(...) or Array(...) did not match Array(...).
