testDynamicClassGeneration: fix test class hierarchy

because TestZodbDocumentComponent contains test specific to Document
Component, tests for other component should not inherit from it, because
tests that apply for Document Component only does not apply for other
components.

The correct base class containing tests that apply to any type of
component is _TestZodbComponent

TestZodbDocumentComponentReload was another case, this test tests some
special cases of document edition/reload, it does not need to extend
TestZodbDocumentComponent, otherwise it will run again all tests from
TestZodbDocumentComponent.
