tests: odb: use correct OID length

pks-t · pks-t · commit 983e627d1021 · 2017-06-13T11:41:29.000+02:00
The `search_object` function takes the OID length as one of its
parameters, where its maximum length is `GIT_OID_HEXSZ`. The `exists`
function of the fake backend used `GIT_OID_RAWSZ` though, leading to
only the first half of the OID being used when finding the correct
object.
