[pkg] Prepare 3.20.8

[js] simplify cw.log implementation There's no need to rebuild and array and join its content, just call console.log with ``arguments``. The only trick is that console.log must be called on a console instance.

[web/views] don't force http redirect on logout We no longer forbid anonymous browsing on https, so we can keep the same scheme when logged out. Closes #5507479.

[views/schema] extract a hardcoded css class attribute
