Add more test-cases

[Deleted user]

Hi. For some reason I don't like to use the Lockfile. I'd like to find out what's the difference in speed when I have cache and node_modules folder, but no Lockfile.

Yarn has such test at https://yarnpkg.com/lang/en/compare/ but it's outdated.

Missing test-cases:
✔ Warm Cache ✔ node_modules ✗ Lockfile/Shrinkwrap
✗ Warm Cache ✔ node_modules ✗ Lockfile/Shrinkwrap
✗ Warm Cache ✔ node_modules ✔ Lockfile/Shrinkwrap
