[auth] Bugfix/auth icons with period (#3559) ...

## Description

Previously it would check if the substring that precedes the first `.`
or `(` of the lowercase spaceless provider title was a valid icon.

Now: 
1. Checks if lowercase spaceless provider title is valid icon
2. If the title contains a `(` it checks if the preceding part of the
title is a valid icon
3. If the title contains a `.` it checks if the preceding part of the
title is a valid icon

| Provider Title | Previous Check | Now Checks |
| -------- | ------- | ----------|
| Login.gov | `login` ❌| `login.gov` ✅ |
| GOV.UK (Brian) | `gov` ❌| `gov.uk(brian)`❌ then `gov.uk` ✅ |
| PayPal.com (Visa) | `paypal` ✅ | `paypal.com(visa)` ❌ then
`paypal.com` ❌ then `paypal` ✅|
| Amazon.com | `amazon` ✅ | `amazon.com` ❌ then `amazon` ✅|
