[PATCH v3 3/5] t4301: verify that merge-tree fails on missing blob objects

From: Johannes Schindelin <johannes.schindelin@gmx.de>

We just fixed a problem where `merge-tree` would not fail on missing
tree objects. Let's ensure that that problem does not occur with blob
objects (and won't, in the future, either).
