fix: ensure module state is in scope for modulep!

Otherwise, doom-module-from-path (and modulep!) would fail to detect the
module they're in, or at least, modulep! would incorrectly return nil,
even for enabled modules.

This issue is what would've caused the package list or the doctor to
include/consider packages in disabled modules or behind disabled flags.
