Closes: #4420 

Created a new error ErrInvalidHeaderwhich can be formed during the verification process verifier.go and will result in the replacement of the primary provider with a witness by executing: replacePrimaryProvider()

Co-authored-by: Anton Kaliaev <anton.kalyaev@gmail.com>

Closes #3935

error itself is not enough since it only signals if there were any
errors. Either (types.SignedHeader) or (success bool) is needed to
indicate the status of the operation. Returning a header is optimal
since most of the clients will want to get a newly verified header
anyway.
