cmd/cli: set ProxyLogger correctly for interactive commands

The ProxyLogger must only be set after mainLog is fully initialized.
However, it's being set before the final initialization of mainlog,
causing it still refers to stale old pointer.

To fix this, introduce a new function to discard ProxyLogger explicitly,
and use this function to init logging for all interactive commands.
