If the developer is missing any dependencies, for instance `github.com/spf13/cobra/cobra`, `go install` will fail:
```bash
../../spf13/viper/util.go:29:2: cannot find package "gopkg.in/yaml.v2" in any of:
/Users/campoy/src/golang.org/x/go/src/gopkg.in/yaml.v2 (from $GOROOT)
/Users/campoy/src/gopkg.in/yaml.v2 (from $GOPATH)
```
While `go get github.com/spf13/cobra/cobra` will build the tool successfully.
As persistent flags of parents can only be added, we don't need to always
check them every time, so make updateParentsPflags return only added flags.

I think It's more obvious now to understand the inheritance of flags.

* Fix shellcheck
Before this change:
In - line 204:
declare -F $next_command >/dev/null && $next_command
^-- SC2086: Double quote to prevent globbing and word splitting.
--- FAIL: TestBashCompletions (0.34s)
bash_completions_test.go:138: shellcheck failed: exit status 1
* Avoid storing pointer to nil
Before this change, the new test fails with:
--- FAIL: TestSetOutput (0.00s)
command_test.go:198: expected setting output to nil to revert back to stdout, got <nil>
Docker (https://github.com/docker/docker) now
also uses Cobra for the CLI. A majority of the
commands have been migrated (still some left),
but adding it already :)
