patch: make diff --git to differentiate b/w file is empty or doesn't exists

Before this patch, as we didn't differentiate the two cases of a file in a context:
1. File doesn't exists
2. File is empty
which causes the blob id to be same for both the cases.

Now we use `nullhex` for a file which doesn't exists in a context (aligning it with
the git diff format)

Changes in test file reflect the fixed behavior.

# Disable the $CAP wire protocol capability.

if test -z "$CAP"
then
    echo "CAP environment variable not set."
