From: mugdha <mugdhapattnaik@xxxxxxxxx>
Currently, running 'git submodule deinit' on repos where the
submodule's '.git' is a folder aborts with a message that is not
exactly user friendly. Let's change this to instead warn the user
to rerun the command with '--force'.
This internally calls 'absorb_git_dir_into_superproject()', which
moves the '.git' folder into the superproject and replaces it with
a '.git' file. The rest of the deinit function can operate as it
already does with new-style submodules.
We also edit a test case such that it matches the new behaviour of
deinit.

submodule: absorb git dir instead of dying on deinit
We also edit a test case such that it matches the new behaviour of
deinit.
I have changed the 'cp -R ../.git/modules/example .git' to 'mv
../.git/modules/example .git' since, at the time of testing, the test
would fail - deinit now would be moving the '.git' folder into the
superproject's '.git/modules/' folder, and since this same folder
already existed before, it was causing errors. So, before running
deinit, instead of copying the '.git' folder into the submodule, if we
move it there instead, this functionality can be appropriately tested.
Changes since v1:
* Removed extra indent within the if statements
* Moved absorb_git_dir_into_superproject() call outside the if
condition checking for --quiet flag
Thank you, Mugdha
