Marco André Dinis 83a32f49e1 tsh: ignore empty or non-existing config files (#11495)
If the newly created config.yaml didnt exist we would load the default
values and continue the flow
However, we were not resetting the `err`'s value and would have an ERROR
message at the end and an invalid exit code

Most of the commands would reset that variable to the output of the
command's execution
One of them was not: `tsh version`
The version command has no return value, so the program would execute
as expected until the last statement: `trace.Wrap(error)` which would
re-use the `err` variable whose value is the result of the `loadConfig`
method.

We could either reset the `err`s value inside the `PrintVersion` switch
case block or reset it right after we check for `IsNotFound`.

We ended up picking the first option as it seems cleaner

```
 # before
$ make full > /dev/null; build/tsh version

 # after
