Callum Waters f934ca82fc lite2: don't save intermediate headers (#4452) ...

closes #4426

The sequence and bisection methods no longer save the intermediate headers and validator sets that they require to verify a currently untrusted header.

## Commits:

* sequence and bisection don't save intermediate headers and vals

* check the next validator hash matches the header

* check expired header at start of backwards verification

* added tests

* handled cleanup warning

* lint fix

* removed redundant code

* tweaked minor errors

* avoided premature trusting of nextVals

* fix test error

* updated trustedHeader and Vals together

* fixed bisection error

* fixed sequence error for different vals and made test

* fixes after my own review

* reorder vars to be consistent

with the rest of the code
