[PATCH 2/2] t5704: Test prerequisites with empty commit messages

[Lukas Fleischer <git@cryptocrack.de>]

While stating that commit messages of prerequisites are optional in
bundles, we used to disallow prerequisite lines consisting of an object
name only. This behavior made `git bundle verify` and `git bundle
unbundle` reject bundles that contain prerequisites without any commit
message.

Add a test to reproduce this behavior.
