Revert "NodeStarter.TestNodeParameters: Allow enabling the web interface"

This reverts commit 18bdf9fcb6138572b9d2c2df101b43a4d605bafa.
- I tried enabling the web interface in WOT unit tests but the node will
fail to start with the web interface enabled because the bookmarks.dat
is missing and I don't want to dig too deep into this. I will rather
adapt WOT to disable its own web interface if the fred one is disabled.
