…results and continuation params

add the indices to meta.index on get as they are defined when
setting them via ```meta.index = { foo: 1, bar: "baz" }``` on save.

FIXES mostlyserious#183

… of Object[Object], because buffer is often looks like:

{
   phase: 0
   error: "[{<<"lineno">>,466},{<<"message">>,<<"SyntaxError: syntax error">>},{<<"source">... (length: 92)"
   input: "{ok,{r_object,<<"users">>,<<"b1f0e0b64f8143a6a45977db8e29ff89">>,[{r_content,{di... (length: 515)"
}

either we use asi or we don't mixing is bad

Since just dumping data in Riak without ever cleaning up is not nice I
added a cleanup for all writen keys in the tests. This should also make
sure that we don't have dependend tests

Also commeted out search tests relying in pre solar functionaliy

this should only return the keys added (4) since we clean the bucket
between tests

environment is set on Travis

only expect keys this tests explicitly saves

otherwise riak.conf will be ignored due to a present app.config

locally 1 sec is more than enough wait for indexes to propagate but on
travis this seems to not be the case let's see...
