Computer doesn't always seem to find all words

[fcarsten]

Sometimes the result list misses valid words. The behaviour is non-deterministic, ie it doesn't always trigger for the same board. Probably a race condition, potentially around the use of postValue().

Example. Computer failed to find the word SUED (Süd). Confirmed that it not related to the Umlaut as the computer finds it just fine when running in Android Studio Device Emulator with the same board and dictionary.
