Relink not working as intended

When executing the same example twice, it asks me also in the second run to decide which account. This UX needs to be re-evaluated as I think it should not ask for account again

https://github.com/bitshares/beet-js/blob/develop/examples/bitshares/signedMessage.js

Start with examples/bitshares/signedMessage.js and reproduce the example twice, noting when account selection appears. Trace the relink flow used by the example and determine why the second run prompts again. Done means the repeated run no longer asks the user to choose an account when the existing link can be reused.
