Add riak_test for object list after deletes

Tests #654. The test currently fails, the next commit will fix it.
Don't skip past empty common prefixes

Fixes #654. If the list of so-far-matching common prefixes is empty, we
shouldn't try and skip past the last (sorted) common prefix. Otherwise,
we try and call `lists:last/1` on the empty list.

Bugfix/handle mark as pending delete
Never rewind when skipping keys in keylist

Fixes
[this](https://github.com/basho/riak_cs/pull/655#issuecomment-23309088)
issue comment. When skipping past a common prefix, we used to mistakenly
skip past only the last common prefix in the state record. There could,
however, be a later-sorted common prefix in the result set. So we now
skip past the exact common prefix that the last result is (if it is
one), instead of the last common prefix in the common prefixes field.
Include prefix in `common_prefix_from_key`
Add two more regression tests for #654

Based on feedback from @shino.

Handle undefined `props` in manifests

Prior to Riak CS 1.3.0 (667319391c4ef3d5c0d757e11952a5202cc64050 in
particularly), manifests were written with `undefined` in their `props`
field, despite the record definition setting it to `[]`. This change
fixes the manifests as they are read, and 'upgraded'. That way, the rest
of the code-base can assume the field is a proper proplist.
