Fix nuxt mode
This MR includes two things:
-
It sets the
ssr
setting instead of themode
setting in thenuxt.config.js
. Themode
setting is deprecated. -
It adds the
utils
folder to the test coverage. This change is already done in !51 (merged), but in order to have it anyway (regardless of the stage of !51 (merged)), I want to include it here as well.
