fix: Lunchflow pending transaction duplicates, missing from search and filter (#859)

* fix: lunchflow parity with simplefin/plaid pending behaviour

* fix: don't suggest duplicate if both entries are pending

* refactor: reuse the same external_id for re-synced pending transactions

* chore: replace illogical duplicate collision test with multiple sync test

* fix: prevent duplicates when users edit pending lunchflow transactions

* chore: add test for preventing duplicates when users edit pending lunchflow transactions

* fix: normalise extra hash keys for pending detection
