Subject: [FIX] web: JournalDashboardGraph widget crash Mk.II

Hardening of commit:995610c065bf0242cb5023cfad2940234395739e

The JournalDashboardGraph requires nv, which is lazyloaded.
However it requires nvd3.js which is loaded after nv.d3.js.
A function called in destroy is defined by nv.d3.js,
which can make the crashhappen with the right (wrong) timing.
