This method is called for every contact on a thread in the thread list, so I figured we should see if one version was faster. I ran this test code:
```
d = Date.now(); for(var ii = 0; ii < 10000; ii ++){ $n.AccountStore.accountForEmail("ben.gotow@gmail.com") }; console.log(Date.now() - d);
```
The other approach which calls meUsingAlias takes `3784ms`, and this version which uses the alias contacts cached in aliases() only takes `264ms`. Confirmed that the tests still pass.
This fixes#393.
The name "Olivia" was being caught in our parser designed to shorten "Mike Kaylor via LinkedIn" to "Mike Kaylor". We now check that "via" is it's own distinct word in the phrase.
