* Fix tx-pool returning the same transaction multiple times This fixes a bug that lead to returning the same transaction multiple times when iterating the `ready` iterator. Internally the transaction was kept in the `best` list and could be duplicated in that list be re-inserting it again. This `best` list is using a `TransactionRef` which internally uses a `insertion_id`. This `insertion_id` could lead to the same transaction being inserted multiple times into the `best` list. * Update client/transaction-pool/src/testing/pool.rs Co-authored-by: Nikolay Volf <nikvolf@gmail.com> Co-authored-by: Nikolay Volf <nikvolf@gmail.com>

License
- Substrate Primitives (
sp-*), Frame (frame-*) and the pallets (pallets-*), binaries (/bin) and all other utilities are licensed under Apache 2.0. - Substrate Client (
/client/*/sc-*) is licensed under GPL v3.0 with a classpath linking exception.
The reason for the split-licensing is to ensure that for the vast majority of teams using Substrate to create feature-chains, then all changes can be made entirely in Apache2-licensed code, allowing teams full freedom over what and how they release and giving licensing clarity to commercial teams.
In the interests of the community, we require any deeper improvements made to Substrate's core logic (e.g. Substrate's internal consensus, crypto or database code) to be contributed back so everyone can benefit.
