Fix getAll part of Issue 150, fix issue where read repair was not invoked for getAll and cleanups.

- Extract fillRepairReadsValues method and use it from various places in get and getAll.
- Fix issue where read repair would not be invoked in getAll when retrieving values from
extra nodes.
- Fix issue where read repair would be invoked once per key in getAll even though
we only need to do it once overall.
- getAll was also affected by Issue 150: Missing keys are not added to node when
performing read-repair. Fix it.
