Hikari does not handle SQLFeatureNotSupportedException in PoolBase.setupConnection when setting autoCommit

[Nyefan]

While fixing issue 1116, calls to connection.getAutoCommit() and connection.isReadOnly() were added to gate calls to the associated setters in PoolBase. However, this breaks integration with the mongo-jdbc-driver as getAutoCommit() throws a SQLFeatureNotSupportedException because the driver acts as though autoCommit is always false.

As per the Connection documentation, "if setAutoCommit is called, and the auto-commit mode is not changed, the call is a no-op", so I believe the correct way to handle this would be to remove the gates, but I believe the following would work as well:

try {
  if (connection.getAutoCommit() ~= isAutoCommit) {
    connection.setAutoCommit(isAutocommit);
  }
} catch (SQLFeatureNotSupportedException {
  // pass;
}
