[SPARK-][Build] Cleans lib_managed before compiling with Hive 0.13.1
This PR tries to fix the Hive tests failure encountered in PR #3157 by
cleaning `lib_managed` before building assembly jar against Hive 0.13.1 in
`dev/run-tests`. Otherwise two sets of datanucleus jars would be left in
`lib_managed` and may mess up class paths while executing Hive test suites.
Please refer to [this thread] [1] for details. A clean build would be even
safer, but we only clean `lib_managed` here to save build time.
This PR also takes the chance to clean up some minor typos and formatting
issues in the comments.
