Trolli Schmittlauch 1fc264a226 manage logging via file handle
reason: `appendFile` combined with lazy evaluation lead to exhaustion of
open file descriptors, as each file is opened again for each write and
due to lazy evaluation is kept open multiple times.

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

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
