Set the null value in the same format

[DmitryFurs]

Description

\Migration\Handler\SetValue and \Migration\Handler\SetValueAttributeCondition have a different declaration for setting the null value. If we use \Migration\Handler\SetValue, we need to specify NULL in uppercase. And if we use \Migration\Handler\SetValueAttributeCondition, we need to specify null value in lowercase. Also for \Migration\Handler\SetValueAttributeCondition, a comparison of the provided value with null string will be performed for each record in the table.

If we pass values in the wrong format, the value will be inserted as a string.
