Crash when unlinking briar and mailbox + wifi off

Steps to reproduce

• in Briar go to settings and open the Mailbox status screen
• If mailbox is running, on this status screen tap on Unlink.
• a Dialogue box will come up asking the user to confirm the unlinking
• before tapping on Unlink on this dialogue box, go to the device settings and switch the wifi off
• Then return to Briar and tap on the unlink that is still showing in the dialogue box

Expected results

• Briar should handle it gracefully and continue the unlinking process either frm teh dialogue box or from the status screen

Actual results

• Briar crashes when I tap on unlink on the dialogue box

I also sent reports from the device itself. I used Pixel 2 phone.

A bit of a corner case, true, and not very probable in reality... so not the highest priority
