Route is matching partial string

Given 2 'host' routes "me" and "home":

``` objc
self.router[@"me"] = ^(DPLDeepLink *link) { .. }
self.router[@"home"] = ^(DPLDeepLink *link) { .. }
```

entering via `[protocol]://home` actually matches the first handler for "me" (since ho[**me**])

This can be worked around by swapping the order of the route handlers, but I figured it would be a good thing to fix the matching regexp.
