Creator complains about git version when git is not configured but opening a file of a repository

Steps to reproduce:

• make sure git cannot be found in PATH and is not configured inside Tools -> Options -> Version Control -> Git
• create or open a simple Qt project (I've used Qt UI example project)
• use a kit that is configured to use a Qt which is inside a git repository
• start debugging by pushing step into and push step into again and again until you're inside a Qt class inside the repository

Current behavior:

• Creator complains about an unsupported git version

Expected behavior:

• Creator does not complain until git is configured or just tells me I'm inside a repository but having no git configured or in PATH
