homepage option doesn't affect web_modules paths

[danprince]

I'm trying to deploy a Snowpack project to a platform that hosts all the static content in a directory which means that I can't use absolute paths.

I've tried using the homepage config option (and also tried it as a CLI flag) but after building, references to installed modules are still absolute (e.g /web_modules/xyz).

I was expecting to do something like this: snowpack --homepage /foo and then see all absolute urls of the form /foo/web_modules/xyz.

Will be resolved as a part of #441
