also str representation of unicode character is different.

for same reason as the xhtml_style version, there is no problem with
having more than one listbox, see d2dedca3 (core: remove useless log

This makes consistent method resolution order with python3 and reveal a
problem that relation field widgets render_pdf was not the expected one
on python3, solve this by defining explicitly the method.

This assertRaises syntax does nothing on python2 and was an error on
python2. Update the test to test the actual behavior

When trying to use `MemcachedTool` without the `python-memcached` package,
a dummy implementation is supposed to allow installation while giving a
warning when called.

This dummy implementation was broken because it was calling a wrong class,
named `_MemcachedTool`, which did not exist. Instead, `_MemcacheTool` did
exist and was used for the real implementation.

This commit renames `_MemcacheTool` to `_MemcachedTool` to allow dummy
implementation to work.

With python2, iterating on a dictionary or a set always produces the same result,
although this is not a documented behavior. On python3 this is not the case,
because the hashing algorithm is random by default, which can also be set using [`PYTHONHASHSEED`](https://docs.python.org/3/using/cmdline.html#envvar-PYTHONHASHSEED). On SlapOS, this is done with nexedi/slapos!1535 

This fixes the parts where ERP5 code depends on python2 order, mostly tests, but also places
where we iterate on a dictionary or set. Most of the time, the fix has been to sort so that
the order is deterministic regardless of the hash algorithm randomization, but sometimes we
had to extend a bit the configuration where the order was really important. We did this after
discovering the problematic areas by running tests multiple times with different hash randomization
seeds. It's not impossible that changing from "default python2 order" to "sorted" reveals some
more problems in custom configurations, but this would mean that the configuration must be 
adjusted to use explicit order instead of being lucky with the default python2 order.

The main pattern was the use of `edit` method which edits properties in an order that is a bit
constrained with the `edit_order` mechanism, because some properties depend on other properties,
so it's important to set them in order. This extends a bit the `edit_order` mechanism to specify
more properties that were edited in the right order with `PYTHONHASHSEED=0` by chance.

This also extends delivery builders to edit properties in order defined in the equivalence tester,
most equivalence tester were already properly configured, except the `start_date` and `stop_date`
from delivery level movement groups. That probably only matters for some specific test assertions,
but in practice this was visible in a lot of failing tests.

Some visible changes are that:
 - workflows are now sorted alphabetically on history tab
 - properties are now sorted alphabetically on the diff view of history tab
 - business templates are installed in the order of dependencies and in alphabetic order when they
  are not constrained.
