Test that all presearchers correctly handle ANYTOKEN

* Move ANYTOKEN handling into TermFilteredPresearcher
* ANYTOKEN is now stored in its own special field - per-field handling is
  delegated to CUSTOM token types
* GenericQueryTreeBuilder emits an ANYTOKEN if extractTerms fails
* Remove DefaultPresearcherComponent (all functionality now moved directly into
  TermFilteredPresearcher)
