[form] fix #719285, due to multiple calls to restore_previous_post, by proper refactorings * move __init__ code from FieldsForm to Form. Must behaviour here should actually be in the Form base class * avoid buggy duplicated call to restore_previous_post * move some code that was in the form renderer to the form'__init__ method (__redirectpath & __form_id hidden input handling)) * 'formvid' should now be specified on form selection, not on form rendering

[fix] Apply fulltextindexed change in the actual index Change of the fulltextindexed attribute of a CWAttribute did actually change anything for already existing entity (but apply to new one). This patch fix this behaviour: * A new SingleLastOperation, UpdateFTIndexOp, to reindex entity whose ftindexation changed during a commit. This data is read from session.transaction_data['fti_update_etypes'] * The SourceDbRDefUpdate operation to store Etype who modify they fulltextindexed of attribute in session.transaction_data['fti_update_etypes']. * A new test is added to check the behaviour
