fix svg definition as in some images the namespace is not
well defined by using xmlns="http://www.w3.org/2000/svg" instead
of xmlns:svg="http://www.w3.org/2000/svg"

Those are the cases of the images generated from OO to SVG conversions.

The image comparation isn't advanced enough to identify minor color
 changes when convert to grey scale. So use simpler images to make
sure we do not get false positives.

The goal of image comparation is only for make sure background is
placed at the figures.

With imagemagick providing a good support for rsvg-convert, those failures
are not expected anymore.

This merge include fixes for some functional tests and
testRunMyDocConfiguratorWorkflow.

add test to check that the method getInstancePropertyAndBaseCategoryList returns properties from property sheets correctly

Extend method getInstancePropertyAndBaseCategoryList to be possible get property sheets from portal_type objects i.e portal_types/Foo. And refactor code to get properties from object inside portal_property_sheets i.e SimpleItem, DublinCore

which is not correct.

They duplicate [gs]etDefaultActivateParameterDict on ActiveObject.

This reverts commit 43b1531d.

=> It introduce testERP5Credential regressions

- avoid random failures by stopping relying on calculation time
- really make sure if the cached method is called or not
- make the test much faster by avoiding long calculation that
  are not needed any more

Drop a quite bit amount of code duplication on tests and few others
useless copy & paste duplications.

Those tests are fixed but (specially run my docs), the implementation
is a bit poor.

(cherry picked from commit c55d31d748329c08428e6b49ee87556d48201003)

- do not make the test dependent on external web site
  (test was using http://www.erp5.org/dists/snapshot/bt5/)
- do not make the test dependent on generic bt configuration.
  If we change dependency of erp5_base, this will not break
  the test any longer
- use dummy repository for testing purposes

This often happens during reindexation of many objects:
the number of processable grouped messages often exceeds 100
and 1 extra message is reserved for nothing.

This fixes a regression caused by f02bc341
("CMFActivity: automatically reselect messages in 'processing=1' state").

Due the lack of rsvg-convert on current slapos setup, it will make those
tests fail. As soon this become available, those tests will pass.

If the official repository was stuck for some time, of if
the revison of erp5_base was increasing in a too fast way,
this was making this test failing.  Also it would be better
that this test use a fake repository
