DHT provide test is broken

[vmx]

Due to a10e3d5 the DHT provide test is broken.

You can reproduce it locally with running:

npx aegir test -t node --files test/interface/dht.spec.js

The error is:

  1) .dht
       .provide
         regular:
     Error: block Qmd7qZS4T7xXtsNFdRoK1trfMs5zU94EpokQ9WFtxdPxsZ not found locally, cannot provide

We now have all tests passing on master. (Didn't really get to see this error happen, locally or CI)
