The revision dd3f918cafebe26e5aa9dff1b2e484b7ed662140
introduced a regression:
it was no longer possible to set an icon in the import module,
and if no icon is provided,
the icon should fall back to the base module icon,
which wasn't the case either.
In this last case, it even leaded to a crash:
```
File "/home/odoo/src/14.0/odoo/odoo/addons/base/models/ir_module.py", line 251, in _get_icon_image
with tools.file_open(path, 'rb') as image_file:
File "/home/odoo/src/14.0/odoo/odoo/tools/misc.py", line 176, in file_open
return _fileopen(name, mode=mode, basedir=base, pathinfo=pathinfo, basename=basename, filter_ext=filter_ext)
File "/home/odoo/src/14.0/odoo/odoo/tools/misc.py", line 211, in _fileopen
raise ValueError("Unknown path: %s" % name)
Exception
ValueError: Unknown path: /base/static/description/icon.png
