Add more unit test for EncryptAlgorithmMetaData, EncryptRule and EncryptTable

[strongduanmu]

Hi, community:

This issue is to add more unit tests for the EncryptAlgorithmMetaData, EncryptRule and EncryptTable classes. Welcome to claim them.

The specific subtasks are as follows:

• Add unit test for EncryptAlgorithmMetaData#isQueryWithCipherColumn
• Add unit test for EncryptRule#isQueryWithCipherColumn
• Add unit test for EncryptTable#getQueryWithCipherColumn

Through this issue, you can understand the process of participating in Apache ShardingSphere, and be familiar with Encrypt-related APIs.
