Extended the migration process with a generic way of applying custom
migration code on top of the SQL files. The implementation provides
a safer way to run GO code along with the SQL migrations and possibility
of rolling back the changes in case of failure to keep the database
consistent.
This custom GO migration is needed to extract the status from
the JSON blob receipt and store it in transfers table.
Other changes:
- Add NULL DB value tracking to JSONBlob helper
- Index status column on transfers table
- Remove unnecessary panic calls
- Move log_parser to wallet's common package and use to extract token
identity from the logs
Notes:
- there is already an index on transfers table, sqlite creates one for
each unique constraint therefore add only status to a new index
- the planned refactoring and improvements to the database have been
postponed due to time constraints. Got the time to migrate the data
though, extracting it can be done later for a more efficient
implementation
Update status-desktop #10746
