wallet: ignore a repeated global currency entry on IndexedDB

The row id is generated, so putting a record that is already stored inserted a
second row and violated the unique index over the three identifying fields,
which aborts the whole transaction rather than just the one statement.  sqlite
already ignored the duplicate.
