Trolli Schmittlauch ab9d593a1b bugfix: fix wrong partial Response sender access

  Request, by `senderID` of a Response

  of an existing cache entry

Trolli Schmittlauch b23201a49c Make key lookups fail after request exhaustion instead of providing default 
Returning the own node as a default does not make sense in all contexts:
Especially for bootstrap joining this can be harmful, so signalling
instead that the lookup failed makes distinguishing on a case by case
basis possible.

Also contributes to #57
