This reverts commit f74f420e.

Such default parameters prevent even entering the module once the document
count is large enough.

Do log it, but do not let it propagate.

Since early days of @arnau work on ERP5 components, we have pylint integrated as a way to check the code in components and in python scripts but nothing prevents us from commiting code with lint errors, leaving the problem for the next developer. 

For this, I extended [`CodingStyleTestCase`](https://lab.nexedi.com/nexedi/erp5/blob/88e4b34ff67aa07447f81c8af836feba607843e8/product/ERP5Type/tests/CodingStyleTestCase.py) that was introduced for very similar purpose so that it also  use our tool to check python code. This way,  we can have failing tests when the code do not pass pylint.

What's still not good is that if we want a business template to be tested, we have to explicitly add a test for this business template, but it's also the case for all our "static" tests (naming conventions, HTML validation etc).


A missing feature was that there was no way to get an overview of all the reported problems on a business template. For this, I added a report action on business template that uses the same code to display errors in all *python* code from a business template:

![ERP5_pylint_business_template](/uploads/13613199227884f0340b8f1c40ca4418/ERP5_pylint_business_template.png)
( the lines have direct links to edit python code )

Because `testERP5WebCodingStyle` was already here checking `erp5_web` (well not really because it was no longer using `CodingStyleTestCase` correctly) , I fixed all problems reported by pylint in erp5_web. In reality it only took a few minutes to do this.

PS: I don't know exactly how we could integrate javascript linter in all this. We have a [`test_javascript_lint`](https://lab.nexedi.com/nexedi/erp5/blob/master/product/ERP5/tests/testXHTML.py#L171), but it does not test much of the code written recently because it only checks portal skins. @romain and @vincentB maybe have plans for this. Anyway, it's out of the scope of this.

erp5_mysql_innodb_catalog: add safety LIMIT in z_getitem_by_path and z_getitem_by_uid to avoid fetching all rows in case of empty argument.

otherwise Localizer will not work in grouped activity.

business template metadata was not commited

This replaces ERP5Site_checkPythonScriptsWithPyflakes that I guess
nobody was using

CodingStyleTestCase tests by default the last business template returned
in getBusinessTemplateList, but  getBusinessTemplateList returned value
changed overtime and this test did not really test erp5_web

Also name include "ERP5 Web" in test class name, as it tests ERP5 Web.

This is for catalog brain displayed in Listbox.

It exists in portal_types

* explain how to use
* remove useless getTitle method
* fix indentation

[erp5_hal_json_style] Fix ordering of annotations in the test to set the right skin at the beginning

Catalog does not need "resource_uid" when it requested for
"resource_use_uid", so don't spend time computing it.
