Prefer exact match on package name over provides match

When searching for packages which might satisfy given dependency,
aptly was first returning packages which `Provides` mentioned
name. By default aptly is picking up only first match (unless
follow all variants options is enabled), so `Provides:` takes
precedence over exact package name match.

Invert this logic by searching first for package name match.
