Direct mode key stored in mozc::client::Client may not be updated upon config change #1202

Description

I'm coming from fcitx#62 but it seems that this is an issue in mozc's code

direct_mode_keys_ in client.cc (

1. constructor
2. SetConfig

That makes this option is not updated correctly when changing from mozc_tool at runtime. I wonder, if there's a way to allow engine to refresh this changes or detect whether the config is updated? (A.k.a, if there is a way for me to write some code in fcitx to do the right thing)

Steps to reproduce

Change direct mode related key
Use it in client

Expected behavior

Change to direct mode key is updated.

Actual behavior

Direct mode key remains unchanged until engine restart.
