Since the previous commit sorts these modules alphabetically, these
tests won't be flaky and should always result in the same message.

A warm rebuild only passed the recompiled modules to codegen, so the .app
modules list shrank (empty when nothing changed). Fixes #5834.

When a longer guarded string prefix falls through to a shorter one,
the backend re-checked the longer prefix with startsWith before
slicing.

Pattern matching on overlapping string prefixes with guards could
generate incorrect JavaScript. Distinguish hoistable guards from
pattern-bound guards so fall-through to shorter prefixes works.

A path dependency of a git package that resolves to the repository
root produced an empty repo-relative path, stored as path: Some("").
This conflicted with the same package declared directly as a git
dependency with no path (path: None).
