Added delay after toggling a habit and before sorting, update

Follow-up from #1102, with comments addressed.

@kalina559 FYI, feel free to take things from there if you wish to continue, otherwise I'll try to get this merged.

If you have an opinion on the best way to avoid sleeping in these particular tests I can look into it.

Just a random thought, but maybe we could use a multiple of some animation duration, instead of 2000 ms? AFAIK, during test, the duration of all animations are set to zero, so the delay would disappear. In any case, I don't think this is a big issue, since large tests are already very slow.

Ok, val delay = 4 * context.resources.getInteger(android.R.integer.config_longAnimTime).toLong() could work, but it's not set to 0 during the test. Maybe I'll revisit at some other time, but if it's not a concern I'll just merge how it is now.
