Workspace mode - yarn.lock conversion fails with invalid package.json in tests

[rafsawicki]

Issue description:

In workspace mode, it seems like synp tries to read all package.json files in the node_modules, even if they are not the main package.json file for the package. We're trying to convert yarn.lock to package-lock.json and one of our sub-dependencies is resolve package, which includes a bunch of invalid package.json files in their test suite. This causes the conversion to fail with Unexpected end of JSON input error.

Are you reporting a conversion error? Please include a link to yarn.lock / package-lock.json:

Cannot link to the whole yarn.lock, but the relevant parts are

I'm afraid this a side effect of how nmtree works. But we are experimenting on trees generation (depgraph, deptree, nmtree) without fs projections. The PoC is in early stages, but looks promising.
