[ML] AIOps: Fix rerender issue with relative time ranges like "Last 1…

…5 minutes" (#176130)

## Summary

Fixes #176066. Regression introduced in #175289.

Fixes a rerendering issue with relative time ranges like "Last 15
minutes". The memoization didn't work correctly because for the relative
time range we would constantly get updated bounds.
