Fix show edit for fix suggestions attached to comment

We have 2 APIs to preview and apply suggestions. One is /fixes/fixId
and another one is POST /fix:apply without use of fixId.

Gr-apply-fix-dialog uses latter when fixId is PROVIDED_FIX_ID
otherwise it uses former one.

Fix suggestions usually get NOOP fix_id from plugin or backend,
since we cannot use /fixes/fixId for our fix_id, we need to rewrite
fix_id to PROVIDED_FIX_ID to use POST /fix:apply

Another fix in this change improves description where we use same
description as title of <gr-fix-suggestion> component.
