Out of sync manifest & lockfile in the project

Fixing out of sync project warning

Yarn & NPM lockfiles

We are gradually rolling out lockfile support. If a yarn.lock or package-lock.json file is present in a project, we will auto detect these and process the project as lockfile based. 

Sometimes a project may become out of sync between the lockfile and the manifest file. If we detect this we will notify you with a warning as some dependencies will not be possible to test until the files are back in sync. This can be resolved by making sure the default branch of the project has a fully synced up lockfile pushed to it after running `npm install ` or `yarn install`. 

We are actively working on improving our user experience around this new feature with more specific errors, watch this space.
