    app: revert to "gimp-paintbrush-tool" as default tool.
    
    A UI unit test (paintbrush_is_standard_tool()) was expecting the
    paintbrush tool to be the default tool. This actually does not fit with
    my tests as the crop tool was always the default tool if I were to
    delete my config folder and start anew. Yet it was working for the unit
    testing at the very least since `make check` used to work until now, and
    was broken by my change.
    
    Anyway with my new code (commit 31e38fe869) and this additional one, now
    it should work both for unit tests and real usage. So this commit fixes
    both the CI and the originally expected default tool.
    
    For the record, Aryeom also agrees that paintbrush is a good default
    tool for first usage/discovery of GIMP.
