Fix linking local RN SDK packages into the web-components repo

[MantisClone]

Problem

Multiple RN devs have experienced difficulty linking local packages.

• Link RN SDK packages into web-components
• Link web-components into invoicing-template

Investigation required.

Bandaid Solution

Copy/paste the dist/ folder works, but it's prone to human error.

Theories

• Linking pulls in extra directories that it shouldn't. Maybe there's a way to configure the npm link command to exclude a directory.
• Linking multiple levels fails but single level works
• web-components is monorepo so location to run link command depends on whether the dependency is specific to the package, or shared with multiple packages.

Consider using symlinkr tool developed by @aimensahnoun

Maybe fixed by RequestNetwork/web-components#244? @rodrigopavezi to confirm.
