SSG doesn't seem to be able to find a template when using template: '@blueprint' using multisite

[JayGeorge]

SSG doesn't seem to be able to find a template when using template: '@blueprint' using multisite (note: this could also be a problem without using multisite—I haven't tested).

Switching to an explicit template solves this.

How to Replicate

Go into the page in the CP, choose a page from the second site e.g. the home page, and select Map to Blueprint from the dropdown.
e.g. if the blueprint is called 'Home', then this should look for the template in secondsite/pages/home.antlers.html

This indeed works fine if you're running the site as normal, but when running php please ssg:generate it returns the error /second_domain (View [pages.home] not found.)
