Title: Fix bug with nested matchers

Filters need a pipeline assigned to read a manifest from. Match calls
Pipeline#copy. #copy evaluates the block before assigning attributes
like pipeline and rake application. This commit changes copy to build up
the new instance correctly then evaluate the DSL block.
