Main changes:
- Refactor activity API to propagate token identities.
- Extend service to convert token identities to symbols for filtering
multi-transaction
- Filter transfers, pending_transactions and multi-transactions based
on the provided token identities
- Return involved token identities in activity API
- Test token filtering
Also:
- Fixed calling cancel on a filer activity completed task to release
resources
Notes:
- Found limitations with the token identity which complicates things
by not allowing to filter by token groups (like token-code does)
Updates status-desktop #11025
Refactor the filter interface to be an async call which returns
the result using a wallet event
A call to the filter API will cancel the ongoing filter and receive
an error result event
Closes status-desktop #10994
