[FIX] modules: get module path

a translation issue that only appears on Odoo.sh. On the
other systems and locally, everything works fine.
The problem seems to have its source in odoo.tools.translate

Here is the problem:

On the basis of staging (brutus), in the LIMS application, menu Report / Test reports:
* take report 000022. The client is in French.
* click on the button "preview PDF"
-> the values of the "state" column are not translated.

Locally (same sources, same database), these values are well translated.

This field is defined as follows:
```py
state = fields.Selection('get_state_value', string='State', copy=True, required=True)

def get_state_value(self):
return [
    ('init', _('Init')), ('conform', _('Conform')), ('not_conform', _('Not Conform')),
    ('unconclusive', _('Inconclusive'))
]
```
Here's what happens:
When the '_' method is called, another method ("_get_translation") is called.

It tries to determine which module is used. To do so, it is based
on the path (path) and use the "get_resource_from_path" method:
https://github.com/odoo/odoo/blob/16.0/odoo/tools/translate.py#L474



This method iterates over all defined addon paths. On Odoo.sh, these are:

```
'/home/odoo/src/odoo/odoo/addons',
'/home/odoo/.local/share/Odoo/addons/16.0',
'/home/odoo/src/odoo/addons',
'/home/odoo/data/addons/16.0',
'/home/odoo/src/user',
'/home/odoo/src/user/Logicasoft/base',
'/home/odoo/src/user/Logicasoft/lims',
'/home/odoo/src/user/Logicasoft/mail',
'/home/odoo/src/user/Logicasoft/web',
'/home/odoo/src/enterprise',
'/home/odoo/src/themes',
```

The path variable is equivalent to "/home/odoo/src/user/Logicasoft/lims/lims_base/models/lims_analysis_result.py"

As soon as the 'path' variable has a common prefix with one of the paths in the
mentioned list, Odoo considers that it has succeeded in finding the path that contains the module in question.

Locally, the path is: "/home/oli/work/bwt/sh/modules/user/Logicasoft/lims/lims_base/models/lims_analysis_result.py"
And the found path is: "/home/oli/work/bwt/sh/modules/user/Logicasoft/lims/"

But on Odoo.sh, the path found is: "/home/odoo/src/user/"
because Odoo finds that there is a common prefix. This is the case, but another path also has a common prefix: "/home/odoo/src/user/Logicasoft/lims" and this one is the correct one.

The result is that the module found is not the correct one:
- module='Logicasoft' on Odoo.sh
- module = 'lims_base' on other systems

Since the module is not the correct one on odoo.sh, the translation is not found.

Solution
========
when we have a module present in parent and child path we want to take the child path,
which is the long one, so we sort the list of paths by length which ensures that children
have priority on parents.
