Fix dashboard acceptance test (#1618)

DBSQL resources are organized in a workspace structure as of recently.
As such it is no longer possible to use the same name for different
assets. This acceptance test used to use the same name for both
the dashboard and the query and started failing. The solution here
is to use a different suffix for the different resources.
