Issue title should not pull from frames which have been excluded from grouping

### Environment

SaaS (https://sentry.io/)

### Steps to Reproduce

1. Exclude frames from being grouped (e.g. `stack.function:"abc" ^-group`)
2. Trigger error which would be subject to this grouping rule
3. See issue title, which displays the top frame's function, even though that frame was excluded from grouping

### Expected Result

It should pull from the the topmost frame which is included in grouping.

### Actual Result

The topmost frame, regardless of included/excluded in grouping is shown.
