At least to me the latter feels superior. It keeps clutter out of the
home directory putting it in a directory with all other cache files from
other programs. If we continue to put the socket at
~/.git-credential-cache/socket by default then checking
~/.cache/git/credential/socket seems useless since the daemon will check
socket locations provided with —-socket anyways and there is no other
way to create the socket at the new location.

To me it would make sense to check the old location and if it is not 
there then use the XDG location to follow that standard. 

I guess that this is not the same behavior that git config —-global 
(it will only put its configuration file there if .gitconfig is unreadable)
has right now though so we should stay consistent and reverse the precedence
here.

Thanks for the feedback,
Devin
