submodule.c: submodule_move_head works with broken submodules
Early on in submodule_move_head just after the check if the submodule is
initialized, we need to check if the submodule is populated correctly.
If the submodule is initialized but doesn't look like it is populated,
this is a red flag and can indicate multiple sorts of failures:
(1) The submodule may be recorded at an object name, that is missing.
(2) The submodule '.git' file link may be broken and it is not pointing
at a repository.
In both cases we want to complain to the user in the non-forced mode,
and in the forced mode ignoring the old state and just moving the
submodule into its new state with a fixed '.git' file link.
