Config is overwritten when running tests

[rejas]

As mentioned here by @bugsounet the config.js is overwritten when running local tests.

Possible solution: Make a backup of the config before starting the testsuite.

@rejas: is it really urgent or can it wait until v2.26?

I want to try to familiarize myself with the test suite
But if it's really urgent for you, code it :)

No, not urgent at all. Was like this since I remember but now that you mention it, I thought it would be time to write it down
