[Toaster] [review-request][PATCH 3/4] toaster: Guard against builds with no targets

[Elliot Smith]

Although this probably can't happen in practice (builds without
targets), this constraint is not currently enforced in the data model.

In the unlikely event that a build has no target (e.g. in test cases),
this causes a template rendering error.

Rather than rework the data model, add a guard to the template
to prevent it from rendering the target name if there are no
targets associated with the build.
