fix: unit tests not working (#24)

this commit was made because after moving the whole repo from packages/theme to
the template-magento repo unit tests stopped working

this is because all packages in magento2 repo are in the repo root's
node_modules, so packages/theme doesn't contain them normally. this changes in
the context of template-magento

also reverted some changes made during the rc7 release which attempted to fix
the issue
