Undeprecate QueryLog#getType, getQuery and getConsistency

[tolbertam]

I deprecated these field as I intended to remove them with #36, but they are actually nice to have as you don't have to inspect the frame itself. We should change these methods to extract the data from the Frame in the same way they are done today (just don't store them as separate fields).

In the case of EXECUTE, we need to get Query from the prime, so we should always include Query. Type and Consistency however can be extracted from the Frame.
