Reorder Sieve tests
Reorder Sieve tests

This comes from a discussion we had in the xrust track

https://github.com/exercism/xrust/pull/97

Typically tests are ordered from the simplest case to the most
complex/edge-case. Putting the simplest test first lets students get a
passing test faster.

I think this re-ordered set of Sieve tests follows
this standard. The simplest test -- finding no primes -- is now first.
Followed by finding just 1 prime, then a few primes, then a lot of
primes.
