Repeated Filter Effects Query Hashing

### Environment

SaaS (https://sentry.io/)

### Steps to Reproduce

Customer has two N+1 performance issues that appear almost identical, except the preceding DB span has more repetitions of the same filter thus influencing the grouping and causing confusion.

### Expected Result

Repeating filters do not impact query hashing

### Actual Result

Repeating filters cause seemingly identical N+1 issues to be grouped separately

Start by tracing the query hashing and grouping path responsible for N+1 performance issues, then reproduce the behavior with equivalent filters repeated different numbers of times. Done means repeated filters no longer change the hash, so otherwise identical N+1 issues are grouped together.
