Currently, using 'git rm --cached <submodule>' removes the submodule
<submodule> from the index and leaves the submodule working tree
intact in the superproject working tree, but does not stage any
changes to the '.gitmodules' file, in contrast to 'git rm <submodule>',
which removes both the submodule and its configuration in '.gitmodules'
from the worktree and index.
Fix this inconsistency by also staging the removal of the entry of the
submodule from the '.gitmodules' file, leaving the worktree copy intact,
a behaviour which is more in line with what might be expected when
using '--cached'.
Achieve this by modifying the function 'remove_path_from_gitmodules()'
to also take in the parameter 'index_only' denoting the presence of
the '--cached' option. If present, remove the submodule entry from the
copy of the '.gitmodules' in the index otherwise, do the same for the
working tree copy.
While at it, also change the test 46 of the test script 't3600-rm.sh' to
incorporate for the above changes.
