[OE-core] possible typo in kgit-checkpoint

[Robert P. J. Day]

if [ -n "$check_refs" ]; then
    checkpoint_branch=`echo $check_refs | cut -d- -f2`
    verify_branch=`git show-ref $checkpoint_branch`
    checkpoint_tag_name=$check_refs
    if [ -z "verify_branch" ]; then
    ... snip ...

  should that last line read

    if [ -z "${verify_branch}" ]; then

instead?
