Clean up current_query and preserve multiple args

When implementing search for multiple architectures or repositories, I
didn't update this method to accomidate the new query parameters. Clean
it up a bit by not appending/stripping the leading '?' anywhere but in
the template itself, and ensure we can handle multiple of any parameter
passed in. Fixes FS#23180.
