The welcome wizard is part of unity8. unity8 usually loads a QPA plugin called "mirserver" from QtMir, so that is it a mir server.
This log suggests unity8 loaded the "ubuntumirclient" plugin, which is from QtUbuntu. Why it did this we need to figure out. The output of unity8.log would help, as would running unity8 with the QT_DEBUG_PLUGINS=1 env var set.
I'm guessing ubuntumirclient is loaded as a backup if mirclient fails to load.
Possible reasons:
1. mirclient QPA missing, meaning qtmir-{desktop,android} package not installed somehow
2. mirclient QPA plugin not loadable, dlload unhappy with it somehow
