Declare KodiWrapper locally when using reuselanguageinvoker

[mediaminister]

This makes sure all KodiWrapper functions are executed instantaneous and return fresh values when using reuselanguageinvoker

This fixes #560

This makes realtime toggling the "watching activity" setting possible. (Should also work for all other settings)

I've had a similar issue in VTM GO, since the Kodi wrapper is actually only initialised once, the old settings that are read in the first init call are being used. Therefore, you need to read the setting every time instead of using the cached value.

Hmm, just looked at it, and this doesn't seem to be the case. Ignore my comment :)

Thanks for reporting. If VTM GO add-on is not affected, there might be a cleaner fix for this problem.

If we would instantiate in addon_entry.py and then pass it on, would that not help?

Personally I would use a global variable rather than a KodiWrapper object that we have to pass on.
The object is always needed anyway, so I don't see a good reason not to define it as global.

And then kodiwrapper.py would just hold a list of functions (something that would be more portable than what we currently have).

@mediaminister The actual fix is in #575, the problem is that the settings seems to be read only when Addon() is instantiated, which means you don't see any updates to the settings for a reused Addon() instance.
