don't show ads if skin has been purchased, fixed ads not getting removed sometimes (#2196)

## Description:

Now checks if player has any "pattern" flares and does not show ads.
Also set visible=false when hiding ads, sometimes the ads were not
getting destroyed properly.

## Please complete the following:

- [x] I have added screenshots for all UI updates
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [x] I have added relevant tests to the test directory
- [x] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced

## Please put your Discord username so you can be contacted if a bug or
regression is found:
