fb: TRDS some tweaks and fixes (1/2)

some smaller issues fixed and optimizations:

- fix twilightmode was wrong assigned to wrong value
- ligtsensor mode after first immediattely switch it does
  not allow for 5sec to switch again....after the 5sec it switches
  to current state if the sensor changed its state in this time.
  This prevends on the one hand on bad light conditions a permanent
  switch between dark/light as well it does not bring the system into
  troubles due of to much configuration changes at the same time
- get rid completly of the observe for the UI_THEME_MODE value and
  handle all over the UIModeManager
- adapt slimActions and settings to this new behaviour/method
- some cleanup and minor fixes

fb: TRDS change auto detect light conditions method

Currently on critical light conditions it still switches to often between
on and off which results in bad UX and in worse cases to unusable phone
due that it is permanently switching. To prevend that slacken the light mode
level detection and set it when it goes to dark mode way more higher (LIGHT_CONDITION)
and when into light mode back to lower level (DARK_CONDITION)

PS
- 25 looks good

Frameworks: TRDS fix possible UI freeze on auto mode change

- only call on theme mode change when auto mode changes. Under special conditions
  it can happen that it is called twice
- ensure that whenever a mode change is really done to close the notification shade
- minor cleanup
