[When very low memory] Service detection runs forever when certificate is rejected

[rfc2822]

Steps to reproduce:

• Enable Developer options / Don't keep activities to simulate a low memory environment
• Setup with an URL with a bad certificate, for instance https://expired.badssl.com/
• Reject the certificate when the popup appears
• Service detection takes ages / runs forever

Expected result:

Service detection should do all the requests. Every request should immediately be rejected and so service detection should be finished (without success) very quickly.

Suspected reason:

When the certificate trust activity appears, the LoginActivity + model data is cleared. When the detection process is finished, loginModel.baseURI is null and

davx5-ose/app/src/main/kotlin/at/bitfire/davdroid/ui/setup/DetectConfigurationFragment.kt

Line 57 in 53a446b

val baseURI = loginModel.baseURI ?: return

immediately returns without processing the result.

Should probably be done when rewriting the ui.setup classes to Compose.
