Bug fixing

[timiimit]

Sometimes InvalidEpicIDException is thrown in production on GrantXP endpoint and it provides no info on what it tries to convert. I added a specialized log message for said exception to be able to find more info regarding this issue.

Other changes:

• Log improbable amounts of earned XP
• Fix QP wait time response
• Fix bug where SetStars endpoint never actually updated stored amount of stars in DB
