[FIX] web: remove report_assets_common JS from minimal_layout

This assets has a lot of JS that is loaded by wkhtmltopdf without any reasons.
Wkhtmltopdf don't like long js to load (it is why subst has been write inline)

This commit allow to print again (on slowly server) several documents in the
same pdf. Before this commit, the JS was not loaded before the default js-delay
and so the subst function never called with as result a pdf of only 1 page.

After this commit you can again print several documents in the same pdf and
subst function is applied.
