Thank you for the pull request!

Please rebase your branch to the latest master instead of using merge.

git remote add upstream git@github.com:strongloop/loopback-next.git
git pull --rebase upstream master
git push -f

@raymondfeng I had to rebase on branch context-watcher for tests to work.

What I understood is there is new config for the CI, right ?

[raymondfeng]

@ghsamm You should NOT rebase to context-watcher branch as it's still WIP. Your PR branch should be rebased to master only as it's the target for merge.

@ghsamm Here is what I have to do to rebase your PR against the latest master.

git rebase -i HEAD~16 (this opens an editor, you should remove the commits from `context-watcher`)
git remote add upstream git@github.com:strongloop/loopback-next.git
git pull --rebase upstream master
git push -f

Yes I know, I had a weird bug in travis CI so I had to re-rebase the commit for the build to restart. It worked the second time although it is the same commit !!
