Fix exception awarding empty badge to user

Summary:
When awarding a badge to a user without having actually selected a batch to award, do not fail on running a database query with no parameter. Instead, silently fail without an error and reload the page, similar to the behavior of Add Recipients on /badges/recipients/1/ in this case.
Do not throw an Aphront404Response as it would make the Award Badge button in the dialog inaccessible and keep the dysfunctional overlay dialog displayed.

EXCEPTION: (AphrontParameterQueryException) Array for %Ls conversion is empty. Query: badges.phid IN (%Ls) at [<phorge>/src/infrastructure/storage/xsprintf/qsprintf.php:383]

Closes T15825

Test Plan: Go to a user's badges, click the Award Badge button, in the dialog do not select any Badge and click the Award button.
