Summary: The MultiGet test in db_basic_test fails in CircleCI vs2019. The reason is that even Snappy compression is enabled, the first compression type is still kNoCompression. This PR checks the list and ensure that only when compression is enable and the compression type is valid, compression will be enabled. Such that, it will not fail the combined read test in MultiGet.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
This code is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it especially suitable for storing multiple terabytes of data in a single database.
