install: allow installation of local packages

It may not be desirable to host all plugins on npm, allow for local packages to
be installed given a package name with a `file:` prefix.

This is still more restrictive than what yarn would support but allows us to still
verify the thelounge compatibility by reading the package.json file.

`yarn add` messes up with local filepaths and generates a lockfile that is
"outdated" as far as any other yarn commands go, which makes them error out.

For some reason `yarn install` fixes that and hence we run that after an install.
Here's the diff of yarn.lock between the broken state after `yarn add file:$path`
and `yarn install`

The only thing it does is switch an absolute path to a relative one for whatever
reason.
