App crashes on launch, then loses FxA credentials

[cpeterso]

Steps to reproduce

Unknown. This is an uncommon crash when I first launch the app.

Expected behavior

No crash.

Actual behavior

Lockwise on my iPad has crashed on launch 2-3 times over the last week, losing my FxA credentials and forcing me to authorize Lockwise for my Firefox account all over again. When I launch the app, I see the Lockwise splash screen, then the lock screen, then the screen flashes and I see the splash screen again and then first-run sign-in/sign-up screen.

The crash seems to happen when I haven't launched Lockwise for a couple days. I don't think I've seen the crash when just switching back and forth to Lockwise running in the background.

Fortunately my passwords etc are still safe on the Firefox Sync server, but it is a hassle and causes me to have multiple Lockwise connections registered in my Firefox Account's "Devices & apps" settings:

Device & build information

• Device: iPad Air 2 running iOS 12.4.1
• Build version: Lockwise 1.6.2

I have encountered this issue too. It seems to happen mainly when I have no signal or wifi.
