Unable to access HUD on phone when launched through qtcreator

[Nekhelesh Ramananthan]

It is not possible to try out HUD actions when trying an application on the phone launched through qtcreator.

Steps to reproduce:
1. Branch any development app
2. Open the branch in qtcreator.
3. Press Ctrl + F12 to run the application on a mobile device
4. Try HUD actions.

What to expect:
HUD appears with the actions provided by the application

What actually happens:
Empty HUD with no actions

Error message:
[21:28:51] unity::action::ActionManager::ActionManager(QObject*):
 Could not get session bus. Actions will not be available through D-Bus.
 Reason: Error spawning command line 'dbus-launch --autolaunch=11a8c61a5b047c99be6264275220ff68 --binary-syntax --close-stderr': Child process exited with code 1

[21:28:51] unity::action::ActionManager::ActionManager(QObject*):

 Provide your application identifier in $APP_ID environment variable.

I can confirm this. I tried with nik90's branch:
https://code.launchpad.net/~nik90/ubuntu-clock-app/add-hud-support

simply branch it, open with QtCreator and do Build -> Ubuntu Touch -> Run Application on Device

Naturally the actions don't end up to the HUD as the app is unable to access the session bus.

The other thing I see is that it seems that QtC does not set the $APP_ID env variable:
phablet 22127 1.8 7.2 195016 51592 ? Ssl 19:26 0:05 /usr/lib/arm-linux-gnueabihf/qt5/bin/qmlscene /home/phablet/dev_tmp/add-hud-support/ubuntu-clock-app.qml --desktop_file_hint=/home/phablet/.local/share/applications/ubuntu-clock-app.desktop

The proper launch command should be:
APP_ID=ubuntu-clock-app /usr/lib/arm-linux-gnueabihf/qt5/bin/qmlscene /home/phablet/dev_tmp/add-hud-support/ubuntu-clock-app.qml --desktop_file_hint=/home/phablet/.local/share/applications/ubuntu-clock-app.desktop

Log from QtC.

OK, after a wild debugging session the reason for session-bus failing is that DBUS_SESSION_BUS_ADDRESS is not set properly when run direct ssh commands.

this env var can be read on the device from ~/.cache/upstart/dbus-session

The fix is proposed n this MR: https://code.launchpad.net/~bzoltan/qtcreator-plugin-ubuntu/fix_app_id_and_the_dbus_session_adress/+merge/184459

To verify the fix just copy the qtc_device_run_app from this branch to the /usr/share/qtcreator/ubuntu/scripts/ and see if it works the way you expect

bzoltan: it's not "Fix Committed" before the MR is merged. :-)
I linked the branch to this bug so Jenkins can update the bug status as it goes along doing it's job.
