[SPARK-19822][TEST] CheckpointSuite.testCheckpointedOperation: should not
check checkpointFilesOfLatestTime by the PATH string.
## What changes were proposed in this pull request?
https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/73800/testReport/
```
org.scalatest.exceptions.TestFailedDueToTimeoutException: The code passed
to eventually never
returned normally. Attempted 617 times over 10.003740484 seconds. Last
failure message: 8 did
not equal 2.
```
the check condition is:
```
val checkpointFilesOfLatestTime =
Checkpoint.getCheckpointFiles(checkpointDir).filter {
_.toString.contains(clock.getTimeMillis.toString)
}
// Checkpoint files are written twice for every batch interval. So assert
that both
// are written to make sure that both of them have been written.
assert(checkpointFilesOfLatestTime.size === 2)
```
the path string may contain the `clock.getTimeMillis.toString`, like:
```
file:/root/dev/spark/assembly/CheckpointSuite/spark-20035007-9891-4fb6-91c1-cc15b7ccaf15/checkpoint-500
file:/root/dev/spark/assembly/CheckpointSuite/spark-20035007-9891-4fb6-91c1-cc15b7ccaf15/checkpoint-1000

file:/root/dev/spark/assembly/CheckpointSuite/spark-20035007-9891-4fb6-91c1-cc15b7ccaf15/checkpoint-3000
file:/root/dev/spark/assembly/CheckpointSuite/spark-20035007-9891-4fb6-91c1-cc15b7ccaf15/checkpoint-3500.bk
file:/root/dev/spark/assembly/CheckpointSuite/spark-20035007-9891-4fb6-91c1-cc15b7ccaf15/checkpoint-3500
------
```
so we should only check the filename, but not the while path.
