The only check with accounting transactions regarding bank account
was that the bank account is not invalidated. This makes the
constraint more strict by checking that the bank account belongs to
the corresponding entity and also that the bank account is validated.

A few tests needed to be updated to validate the bank accounts. Also
a legacy sequence test has been removed because it is now covered by
normal tests.

The parameter is still named `organisation` for "API stability", but
this parameter can be a person.

This was already used by the fields on accounting transaction for
source/destination_payment and more or less working already, except
for the case where the person had a subordination to an organisation
member of the group, in that case instead of showing the bank accounts
from the person this was showing the bank accounts from the
organisation

On a transaction without section / mirror section, on the profile tab
all accouts where displayed

drop skip_invalidated_bank_accounts option, we are now using
base_category instead.

erp5_accounting, erp5_payment_mean: display currently selected Bank Account even if it is invalidated.

no need to validate them in the test

There is no good reason to prevent editing in cancelled state and
it can be needed, for example to remove a cancelled payment
transaction from a payment transaction group.

This is different from the total of durations of test result lines
because they are executed in parralel on different testnodes. The
actual duration is just the difference between start and stop, so
that we don't have to calculate.

This makes it easier to understand the duration in minutes and hours

Ran https://github.com/python/cpython/blob/3.7/Lib/lib2to3/fixes/fix_asserts.py after adding the missing methods (assertRegex and assertRaisesRegex) on ERP5TypeTestCase.

Also ran a custom fixer rewriting
 
```py
self.assertTrue(a in b)
```

into

```py
self.assertIn(a, b)
```

automaticLayout can not be used with firefox 68 (the browser from test
nodes) because it lacks support for ResizeObserver

triggered manually with "Format Document" of "Format Selection"
actions

This enables usage of @ in quick pick to search for symbols and make
sticky scroll show the current context

   Probably there are missing files but it is a start.

With tweaks to support firefox 68 from test nodes:
 - build with babel, see jerome/monaco-editor-erp5@cf10f2d5
 - special handling of ResizeObserver that does not exist in Firefox
   68: it is used only for automaticLayout, which is not strictly
   needed. So this feature will not work for firefox 68.

Enable sticky scroll
