Fix qtdesignstudio-4.8.0-alpha5 - usage statistics plugin problem

When using the qtdesignstudio-4.8.0-alpha5 snapshot and creating a new project one of the two cases happen:

• It works
• It crashes

I'll list the scenarios here:

• When `UsageStatistic` plugin is disabled and `Enable crash reporting` is disabled - it WORKS.
• When `UsageStatistic` plugin is disabled and `Enable crash reporting` is enabled - it CRASHES.
• When `UsageStatistic` plugin is enabled and `Enable crash reporting` is enabled - it CRASHES.
• When `UsageStatistic` plugin is enabled and `Enable crash reporting` is disabled - it CRASHES.

I don't know if its these are the only discriminatory parameters but behavior listed seems consistent.
