Remove old references for jumpup:integration:check, lock and unlock

I forgot to change the references for `jumpup:integration:check`, `jumpup:integration:lock` and `jumpup:integration:unlock` on this commit https://github.com/Helabs/jumpup/commit/1148b8bfb1b4adbdd894c39a3a52feb3514db0aa

All the these tasks are on jumpup:start and jumpup:finish
