…in the project (#5150)

* fix: should infer package manager from config if there's no lockfile in the project

* fixup! fix: should infer package manager from config if there's no lockfile in the project

Currently, 3 options are implemented:

- options.prune (defaults to `false`) - Remove null or undefined
fields from the object after merging.
- options.merge (defaults to `true`) deep-merge nested fields, note
that dependency fields are always deep merged regardless of this option.
- options.warnIncompatibleVersions (defaults to `true`) Output warning
if two dependency version ranges don't intersect.

Closes #4779

See changelog at https://github.com/vuejs/vue-test-utils/blob/v1.0.0-beta.31/CHANGELOG.md#100-beta31-2020-01-18

New projects will be created with this new version.

There are a few breaking changes since beta.29. So we can't automatically migrate existing projects to this new version. Users can upgrade at their own will.

Commit 1b64ff8 introduced a nested if in `_eslintrc.js` with the same condition than the wrapping one. This changes the condition to check for TypeScript instead.
