[sailjail-permissions] Add a voicecall-ui-prestart profile.

[dcaliste]

This allows to declare the prestart voicecall-ui
as owner of the com.jolla.voicecall.ui
and com.nokia.telephony.callhistory interfaces.

This is related to https://forum.sailfishos.org/t/4-4-0-58-tap-missing-call-doesnt-open-phone-app/10819. The problem is arising from the fact that within sailjail, the prestart voicecall-ui cannot register the com.nokia.telephony.callhistory service because it's not allowed to own it.

I'm not sure this is the right way to solve the problem though it is efficient ;)

I'm not able to reproduce the issue here, and I'm wondering if it might have already been fixed by the changes described in #117?
Essentially, the voicecall-ui-prestart.desktop file was dropped, so the voicecall-ui.profile is now used in all cases.

[llewelld]

Just to clarify, the fixes that actually address the issue aren't in this repo: an updated version of the voicecall-ui app is needed for them.

[dcaliste]

Ok, if it's fixed in voicecall-ui, then it's fine to close this PR.

@Tomin1 would you mind taking a look and confirming whether or not this is fixed please?

It's broken in 4.4.0 because commit 26efe54 was included there but a change to voicecall-ui was not. This must have been a mistake but I'm not sure how it happened. We either need to revert that commit here or include the change to remove voicecall-ui-prestart.desktop in voicecall-ui. Either should be safe to do.

If I understand right the changes to drop voicecall-ui-prestart.desktop were already merged in, so perhaps it would make most sense to cherry-pick those changes to voicecall-ui?

That makes sense to me.

@Tomin1 has cherry-picked the changes in voicecall-ui that will fix this in the next release, so I'll close this PR. Thanks for the contribution @dcaliste which made the issue very clear and saved us a lot of time.

One question maybe @Tomin1 if you have time, since voicecall-ui sources are not public, I cannot check : is the missing commit in voicecall-ui changing the DBus service name for callhistory and putting under com.jolla.voicecall ? Or is it a completely different approach ?

So the issue here was that we have had a separate sandboxing profile (a desktop file, named voicecall-ui-prestart.desktop) for voicecall-ui-prestart.service and that determines which profile file Sailjail uses and that corresponding file was missing because the symlink was removed. The change in voicecall-ui changes it to always use the main file /usr/share/applications/voicecall-ui.desktop so that Sailjail uses voicecall-ui.profile that already exists in the repository. No D-Bus names were changed for that.

Ok, thanks.
