Resolve "Shorten long component tests"

Description

Currently, the valgrind tests are running into a timeout and we cannot see the results of the failing tests. This happened as new component tests (components/03-derivatives-3d.test, components/13-hartree-3d_mg.test) have been added. These should be shortened and eventually moved back to the short-run group, to run on the valgrind builder.

News snippet

Shorten tests and enable on valgrind builders.
