Crash caused by wrong variable

[rm-code]

fatal: Cannot change to '/Users/Robert/Coding/repos/Foovar': No such file or directory
Error: src/screens/SelectionScreen.lua:87: bad argument #1 to 'format' (string expected, got nil)
stack traceback:
    [C]: in function 'format'
    src/screens/SelectionScreen.lua:87: in function 'createGitLogs'

    [string "boot.lua"]:435: in function <[string "boot.lua"]:431>
    [C]: in function 'xpcall'

The crash isn't caused by the missing path but instead by a faulty variable name.
