Commit 0c40c626ca introduced a new
ipa_proto_ccm module, which was not added to the app module
list. Commit 515aa33434 then used a
function from this module. In interactive mode the module would be
loaded automatically so its omission was not detected in testing. In
embedded mode (used by default in relx releases) modules are loaded
statically on startup and must be explicitly listed.
