```
test/xts/acts: fix wifi acts to wait for async callback execution 
 
in multiple wifi testcases the async callback/promise are not actually executed, 
therefore the testcases terminate before the asserts inside the callbacks are 
checked causing the testcases to pass even when things are not actually properly 
working. Fixing by moving the done() functions inside the callback or in the `.then(...`; 
Remove sleeps where not necessary; 
 
Apply to test/xts/acts 
```
