fix(amazonq): Skip prefix matching for Edits suggestions that trigger on acceptance (#7814)

## Problem

For Edits pagination case, we always send discard telemetry even though
there are pending Edits suggestions. The root cause is due to prefix
matching logic (we always send discard telemetry if the prefix does not
match).

## Solution

Skip prefix matching for Edits suggestions that trigger on acceptance
(pagination case)
