Crash when manually signing in to Aurora Store with MicroG

Nobody has claimed this yet.

**Affected app**
Name: Aurora Store Nightly
Package id: com.aurora.store.nightly
version: 4.8.0-9d80b1dd5

**Describe the bug**
Aurora Store (Nightly) crashes when attempting to manually sign with MicroG when **Trust Google for app permissions** is unchecked.

**To Reproduce**
1. Have MicroG installed and add your Google account to it
2. Uncheck **Trust Google for app permissions**
3. Run Aurora Store
4. Go into Settings \> Networking and check Use microG to sign in to accounts
5. Restart
6. Select Allow in the Google Account Manager dialog
7. It crashes.

**Expected behavior**
Aurora Store should sign in without crashing after manually giving it permission to sign in.

**Screenshots**

**System**
Android Version: 16
Custom ROM: LineageOS 23

**microG**
microG Core version: 0.3.12.250932
microG Self-Check results: All ticked, except for work profile which I don't use

**Additional context**
Checking Trust Google for app permissions prevents the crash and Aurora Store signs in and can be used as normal, but I'd rather not just blindly trust all apps to sign in with my account.

I had already reported it to Aurora Store but a dev suggested it seems to be an issue on MicroG's end:
https://gitlab.com/AuroraOSS/AuroraStore/-/issues/1470

No project file or test is identified in the report; begin by reproducing the MicroG sign-in sequence with Trust Google for app permissions unchecked and review the AccountManager cancellation log. Compare the behavior with Aurora Store issue 1470, and consider the issue done when manual sign-in completes without crashing in that configuration.
