Option to show alias only omitting account name

Hi all,

In cone `0.2.20` we have option to search and use any alias defined in ledger file and that works fine. I have recently enriched my ledger file with accounts, to use `--pedantic` error check in `ledger-cli`, and cone started displaying double entries in this case whenever i searched for matching alias.

Example: _wallet_ is used as alias (_wallet_) but cone will display account as well (_Assets:Wallet_), containing matching word. This is functional example for this bug report purposes:

Is it possible to put this on a back log so we can expect this feature in future? Thank you.

Reproduce the search using the reported cone 0.2.20 scenario: an alias such as _wallet_ alongside the account Assets:Wallet. Trace the search and display entry point in the Flutter app; done means an option can show the alias without also displaying the matching account, while preserving normal alias and account searches.
