don't issue critical message when trying to alter sqlite db during test

[test] cleanup

[test] update tests broken by changes on attributes permissions handling in yams (add/delete replaced by update

remove #<formid> from url used to redirect after a validation error

[test] no more __cubicweb_internal_field__ value displayed on password widget

[test] inline-creation requires petype argument to be selectable. Fix arguments order to make it clearer that 'template' is an argument of the test class .view method

[test] skip test when fop failed

[test] don't display progress bar when testing checkintegrity

[test api] rename _user_session to user_groups_session, fix its arguments and return only the session, not (user, session) to make things clearer

auto-delete relation with single cardinality using execute, not unsafe_execute, so permissions are correctly checked

fix tests

add */*.py to default MANIFEST.in to avoid pb such as #719282 in the future

fix #615379 by checking admin user exists instead of making think everything is fine

cleanup, typos

[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
