Martin Atkins 45b04c826a core: don't crash if no module state exists for multi var
For child modules, a ModuleState isn't allocated until the first time a
module instance is inserted into the state under the module's path.
Normally interpolations of resource attributes are delayed until at least
one resource has been created due to the nature of the dependency graph,
but if the interpolation value is a multi-var (splat) then it is possible
that the referenced resource has count=0 and thus created _no_ resource
states when it was visited.

Previously we would crash when trying to access the resource map for the
nil module in order to count how many instances are present. Since we know
there can't be any instances present in a nil module, we now preempt
this crash by returning zero early.

This edge-case does not apply to the root module because its ModuleState
is allocated as part of initializing the main State instance.

This fixes #14438.
