[entity attr cache] mark attribute as uncacheable in the underlying function else we may miss some changes. Also rewrite a storage test currently failing because cache of the entity created by the test transaction, distinct from the entity created internally and given to hooks and all, has its attributes cache not updated. As this doesn't seems a proper usage, rewrite it as expected. Much probably closes #2423719 definitly.

CubicWeb dependencies and standard set of cubes have been fetched and
update to the latest stable version.

You should ensure your PYTHONPATH contains `%(basedir)s`.
You might want to read the environment configuration section of the documentation
at http://docs.cubicweb.org/admin/setup.html#environment-configuration

You can find more cubes at http://www.cubicweb.org.
Clone them from `%(baseurl)scubes/` into the `%(basedir)s%(sep)scubes%(sep)s` directory.

To get started you may read http://docs.cubicweb.org/tutorials/base/index.html.
