Subject: VREF/MAX_NEWBIN_SIZE does not handle deletion

If a reference is deleted in a repository where this virtual ref is
active, the script is not capable of handling it correctly:

remote: fatal: bad object 0000000000000000000000000000000000000000
remote: error: unable to find 0000000000000000000000000000000000000000
remote: fatal: Not a valid object name
0000000000000000000000000000000000000000

This patch fixes the issue.
