Bug: Back Button Opt-Out Bug

[Arique1104]

Describe the bug
When a texter in a campaign opts someone out, and they press the back arrow <--, the screen does something glitchy.

To Reproduce
Expected Behavior Happy Path:

1. Create a texting campaign
2. Click on 'switch to texter'
3. Send three text messages
4. Click the back arrow
5. Expected behavior is to see the name of the person you texted last

Unexpected Behavior Sad Path:

1. Repeat steps above, but this time press the back arrow and opt out your last person texted.
2. Send another text message
3. Press the back arrow and you will see the error

Expected behavior
A grayed out contact who has been opted out and whom the volunteer cannot successfully text.
Be able to go back and forth to every contact on their list without any glitches.

During further review of this bug, the following options were considered:

• removing the <-- back arrow and --> forward arrow from the second section on top of the screen WITHOUT removing the functionality of that section. In essence, keep the pink square and remove the pink circle (check the image attached below.)
• Arrows and counter can both be removed without losing critical functionality for the volunteer texter.
• Further development conversations regarding the functionality of this section will be brought to coalition member's attention for input.
