JdbcTransaction changes autoCommit to true for shared Connections

[hkuhn42]

The constructor for JdbcTranscation with connection should either never trigger a auto commit reset or should check skipSetAutoCommitOnClose flag.

MyBatis version

3.5.13

Database vendor and version

Oracle 19.3 SE2 (probably all other databases)

Test case or example project

Connection conn = null;             // get connection from pool
conn.setAutoCommit(false);
// do something via jdbc
SqlSessionFactory sqlSessionFactory = null;             // create factory with skipSetAutoCommitOnClose
SqlSession sqlSession = sqlSessionFactory.openSession(conn);
// to nothing
sqlSession.close(); // auto commit is set in close, everything  is committed

Steps to reproduce

• Open a connection via jdbc
• Set auto commit to false
• Open a SqlSession
• Close SqlSession

Expected result

• Auto commit is still false, no auto commit is done on close

Actual result

• Auto commit is true, commit is done on close
