we need quick suspend/resume

We suffer from the bug described in https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/issues/321 which seems to be solved with https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/merge_requests/540

In short: after resuming on an incoming call, modemmanager does something like this:

Jun 03 11:22:16 pureos ModemManager[21018]: transaction 0x1 aborted, but message is not abortable

by that time, the call already went to voicemail.

Can we at least get a modmemmanager that includes the option --test-quick-suspend-resume and test-no-suspend-resume ?
