[Bug] When switching ID Sites Matomo throws an error

[Starker3]

When switching to a different website while editing an existing container, Matomo throws an error such as: The requested container "abcdefg" does not exist.

Since a container can only exist for a specific ID Site, it's expected that changing ID Sites shouldn't try to load the same Container ID. Perhaps changing this to an info banner instead of warning/error and expanding the message to be more clear would be helpful to users to understand that the container is specific to an ID Site.

@Starker3 We should try to remove the idContainer on site change to get rid of this error totally if we can't do that atleast change this to a info :+1:

Thanks @AltamashShaikh I'm thinking that it might be useful if it is shown in a different way. Especially for users who are new to Matomo or to the Tag Manager they might not know that a container is specific to an ID Site. When they switch they might then be confused as to why the container is no longer accessible. But I guess if it's simpler to remove the idContainer parameter when changing ID Sites then that might be an optimal solution than changing the warning and copy.
