[glib/wip/smcv/deprecated-prop-followup: 5/5] tests: Run all tests with deprecated property warnings enabled

[Simon McVittie <smcv src gnome org>]

commit 831f5c5c2daf4ce0778f69f3a6d2672922f953c5
Author: Simon McVittie <smcv collabora com>

    tests: Run all tests with deprecated property warnings enabled
    
    The tests that functionally rely on G_ENABLE_DIAGNOSTIC=1 still set it
    explicitly, so that they will behave as expected when run as
    installed-tests or manually.
