Pillow 7.0 changed the default resampling filter from NEAREST to
BICUBIC. Because the logo parser resizes the image before sampling it
and doesn't specify a filter, its behavior changes depending on the
version of Pillow, even if the input image is the same. And there's a
test depending on its output with a fixed image.

Explicitly specify the old default as that's what's in the test.

Behavior before the fix:

Uploading a grayscale image with transparency in the company logo field
of the document layout causes a crash:

```
  File "/data/build/odoo/addons/web/models/base_document_layout.py", line 89, in _compute_logo_colors
    wizard.logo_primary_color, wizard.logo_secondary_color = wizard_for_image._parse_logo_colors()
  File "/data/build/odoo/addons/web/models/base_document_layout.py", line 191, in _parse_logo_colors
    color[1][2] > white_threshold) and color[1][3] > 0:
Exception

...
IndexError: tuple index out of range
```

To reproduce, use the `logo_ci.png` image included in the unit test
data and load it in the document layout (under General Settings).

The system does not detect that the image does not have color
information and attempts to read the R,G,B values (but the image only
has 2 values per pixel: the grayscale value and the alpha)

Versions affected: 13, 14

Behavior after the fix:

The image is loaded correctly (arguably, there is not a lot of interest
in detecting the primary color of a grayscale image, but the script
still returns a (gray) value which is preferrable to a traceback)

Forgotten TODO
Instead of checking in _for_xml_id (where 99% of calls are static),
verify on the few calls that accept an arbitrary argument

The document layout preview is a complete defferent simplified template
with its own css that replicates at best the different styles.
It does not have the external layout features and lack of fidelity.

The new preview actually use the real documents templates and put the
result in an iframe. It now has a high fidelity, though not perfect.

The goal is for a better onboarding, where clients see easely how
documents will look if they had an app to generate them. Of course, the
data on the document is a false invoice.

Refactor all this from base to web.
