This commit is three-fold:
1) we now honnor attributes `create` and `import` which can be
set to a falsy value in archs (and in these cases, we disable
the import feature)
2) we converted the base_import test suite to use the owl views
3) we whitelisted the base_import addon for the lint/prettier
script
