Fix wrong namespace when requesting chart info

[andresmgot]

Description of the change

Fix an issue causing the request for the chart to use the current namespace (_all if all namespaces is selected) rather than the app namespace.

Apart from that, I found a small bug that two releases in different namespaces were using the same key in the list.

[absoludity]

A couple of things confuse the code here, imo:

• the all function argument is actually allStatuses not all apps across namespaces - can we rename it to be explicit (it's always passed as true from the only call-site afaict, so we could even get rid of it).
• the fetchApps and subsequent App.listApps have functionality to support fetching apps across all namespaces which is the cause of this change, but it'd be a lot easier to reason about this code if it was obvious why namespace can't be used here (because it could have the value _all. Perhaps a comment, or renaming it namespace_or_all or something.

Yes, since we have deleted the code for the Hex UI we can delete it.
