[FIX] base: reniew request registry after uninstall

Install and then uninstall the utm module via the web client, you get a
traceback because the ir.http override of the utm module is still
present in the registry altought the module is not installed anymore.

The problem affects all modules that override the _post_dispatch method
of ir.http, it is not limited to UTM.

The problem is that, after the uninstallation, a new registry (without
the uninstalled modules) is created but the old registry was still used
by the HTTP stack.
