[FIX] account: correctly get "Search More" output

Open Bank reconciliation, deactivate some record (-), go to "Manual
Operations" tab, add Analytic Tags using the "Search More" functionality.
Resulting tag will be blank and impossible to delete.

This is because:
1) The field shown is the display name, which is missing.
2) When selecting analytic tag(s) this way an array of
results is returned but it is not handled correclty by the view.
When selecting the analytic tag from the drop down menu a single value
'{id: , display_name: }' is returned.
