[FIX] mail: discuss sidebar quick search case-insensitive

Before this commit, quick search in discuss sidebar (shown when
more than 20 conversations) was case-sensitive. For example,
when a channel was named "R&D" and user types "r", the channel
was not found.

This commit fixes the issue by making search case-insensitive.
