submodule::module_clone(): silence die() message from module_name()
submodule::module_clone(): silence die() message from module_name()

The die() message that may occur in module_name() is not really relevant
to the user when called from module_clone(); the latter handles the
"failure" (no submodule mapping) anyway.

Analysis of other callsites is left to future work.
