Trolli Schmittlauch ab9d593a1b bugfix: fix wrong partial Response sender access 
- replaces improper record field access of `sender`, only existing in a
  Request, by `senderID` of a Response
- fixes the resulting exception-crash
- adds new function that enqueues a verification mark and timestamp bump
  of an existing cache entry

Trolli Schmittlauch f1b15d5a9e bugfix: fix join by adding join node and waiting for it

  itself as a neighbour as well
- wait for migrations from the node

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
