Goutham Veeramachaneni 2fa647f50b Fix missing postings in Merge and Intersect (#77) 
* Test for a previous implematation of Intersect

Before we were moving the postings list everytime we create a new
chained `intersectPostings`. That was causing some postings to be
skipped. This test fails on the older version.

Signed-off-by: Goutham Veeramachaneni <cs14btech11014@iith.ac.in>

* Advance on Seek only when valid.

Issue:
Before in mergedPostings and others we advance everytime we `Seek`,
which causes issues with `Intersect`.

Take the case, where we have a mergedPostings = m merging, a: {10, 20, 30} and
b: {15, 25, 35}. Everytime we `Seek`, we do a.Seek and b.Seek.

Now if we Intersect m with {21, 22, 23, 30}, we would do Seek({21,22,23}) which
would advance a and b beyond 30.

Fix:
Now we advance only when the seeking value is greater than the current
value, as the definition specifies.

Also, posting 0 will not be a valid posting and will be used to signal
finished or un-initialized PostingsList.

Fix bug where having one chunk can cause panic 
When we have only one chunk that is out of range, then we are returning
it unpopulated (w/o calling `Chunk(ref)`). This would cause a panic
downstream.

Fix #59 
Mutating the chunks can change their length. Hence referencing using
previous indices can cause panics.
