Sanitizing the time range doesn't work in this profile

STR:

1. load this profile: https://share.firefox.dev/3sfuhfj
1. commit a new time range
1. upload with unchecking "include the hidden time range"

=> the hidden time range isn't removed

I didn't check if this is working with other profiles yet. In case this is useful, this specific profile was made with "nostacksampling".
