Cache packageName to base Uri mapping.

This makes analysis with using incremental analysis cache 30% faster.
Without this change getBase() takes 40% (!) of total analysis time.
With this change - just 0.79% of total time.

Although the remaining 17% of PackagesBase.resolve() make my cry.
Why URI manipulations are SO SLOW?!
