Fix filter creation flow for capture group insight
Created by: vovakulikov
Prior to this PR if you tried to create capture group insight through drill-down filters flow (save s new view button) you see FE runtime error about that we couldn't parse response properly map isn't a function of undefined
.
This PR utilizes create handler and reuse update handler for handling all possible insight types.
How to test
- Try to create capture group and other insights through drill-down filters (with filters and without)
- Tyr to edit capture group insight or search based insight
