Bug 884050 - [SMS][MMS] Regression. New renderContact rules missed untested cases


https://bugzilla.mozilla.org/show_bug.cgi?id=884050

- Only render a contact's tel value entry for the _specified_ input value when not rendering a suggestion. If the tel record value _doesn't_ match, then continue.
- If rendering for contact search result suggestions, don't render contact tel records for values that are already selected as recipients. This comparison should be safe, as the value in this.recipients.numbers comes from the same source that current.value comes from.
