After bumping some dependency versions, every instruction step is "[object Object]"

[jude]

I made the following changes to package.json. After this point, each instruction steps is displayed as "[object Object]":

I fixed this by commenting out the block at at https://github.com/Project-OSRM/osrm-frontend/blob/gh-pages/src/index.js#L158-L168.

Maybe one of the module updates addressed whatever led to the block being added originally ?

Note I've only looked at the instructions in English so maybe this block is still needed for i18n support.
