Dark Theme doesn't Appy

[sathukorale]

@DSteve595, I think there is something wrong with how the dark theme applies.

If you have the dark theme disabled on Put.io, but choose to enable it, the change doesn't reflect on the app (this is after a restart to the app).
If it already enabled, the very first time you login (yes, you have to logout and login) the dark theme will work. However, from the next run onwards, the theme will revert back to the usual. Changing the setting on Put.io doesn't seem to affect the app.
