Homesets are not "personal" when they are detected two times (1x personal, 1x non-personal)

[rfc2822]

Problem scope

• I'm sure that this is a DAVx⁵ problem.

App version

• I'm using the latest available DAVx⁵ version.

Android version and device/firmware type

No response

Steps to reproduce

Create a DAVx5 account with a service that lists home-sets under multiple principals (e.g. mailbox.org). URL hierarchy:

• the user principal is something like /users/3, which contains both
  • a /carddav / /caldav homeset
  • group memberships in /principals/groups/0 (display name "Addressbooks")
  • and /principals/groups/1(display name "Standardgrouppe").

Actual result

DAVx5 queries the group principals, which again contain the /carddav / /caldav homeset. So the homeset is first detected as personal homeset (directly within the user principal), but then overwritten as non-personal homeset (from the group principals).

Expected result

If a home-set is detected as both personal and non-personal, it should be treated as personal.
