Fixes #16030
Also includes the node_modules folder as discussed on slack to keep matomo working for users who do not have servers with node and deploy from git.
@diosmosis guess if we include the node_modules in core, we might need to remove the automatic npm update
in travis builds again? so we can be sure all files that are needed are actually commited
👍 looks all good from my perspective... be good if @sgiehl confirms too
Looks good to me too. Guess we need to merge the change to travis-scripts to master and update the submodule here before merging...
