      Description

      There are a few places in the query engine which assume that all storage engines which return true for supportsDocLocking() also support RecoveryUnit::getSnapshotId():

      This assumption does not hold for the biggie storage engine. This is currently causing query correctness issues leading to the failure of tests getmore_invalidated_documents.js and ensure_sorted.js. These failures were introduced by the code added in SERVER-42979 which assumed that doc-locking engines also support snapshot ids. There could be additional latent problems of a similar nature that have not yet been discovered.
