WelcomePage test segfaults

Describe your environment

• OS: Ubuntu 24.04
• Jami version: Atlas
• What build you are using: repository

Steps to reproduce

• Can you reproduce the bug: at will
• Steps:
  1. Run .jami-client-qt/build/tests/qml_tests "-input" "-input" "jami-client-qt/tests/qml/src/tst_WelcomePage.qml"
• Actual result: Test segfaults
• Expected result: Test passes

This also causes the build to fail on Jenkins

Originally, it seems that the test fails due to inappropriate access to a no longer valid viewManager object in the callback function of presentDialog. However, removing the access still causes a segfault. The logs imply a possible parenting issue that needs to be investigated further.
