tools: Fix overriding of current_settings.

Settings specified in other command line args take precedence over
profiles and --config, which takes precedence over settings in actual
config files.

Since commit 1e2420bca8 ('commands: new
method for defining commands') commands like this:
  lvchange --config 'global/test=1' -ay vg
have been printing the 'TEST MODE' message, but nevertheless making
real changes.
