[499986] Correctly store engine preferences and fix setting to defaults
There was a bug in obtaining the disabled match engines preventing the
selection to be stored.
This change also fixes the behavior of setting the engine page to
defaults. If there is a default configuration of an engine, e.g. using
the plugin_customization, the "Set to defaults" button didn't take this
configuration into account, but always sets the highest ranked engine.
Moreover, this preference page has been refactored to make it more
readable.
