fix: update test with create-near-app assumptions

[chadoh]

the structure of create-near-app changed in v1 and we need to change this test to match

the commit that changed it is here: near/create-near-app@7ab9ae3

@janedegtiareva I think this will fix the test (Travis didn't complete yet when I wrote this)

However, I think it would probably make sense to add create-near-app to this project's devDependencies and use the local version, rather than using the latest version with yarn create. Do you think it makes sense to do that before we merge this one?

I think that the commit that fixes the --vanilla issue is needed too. I think that we also need to file a docs cleanup issue to remove --vanilla from all the things

Merging to fix the build

[chadoh]

Vanilla is not default until near/create-near-app#387 is merged and published

Note that docs changes are already in draft waiting on that one

It needs a review! Please help if you can

I still think having create-near-app unversioned in these tests is a bad idea. Let’s add it to devDependencies so future interface changes don’t break near-shell until dependabot bumps the version
