Don't ignore force option in InstallCommand

[MrKrisKrisu]

The new Interactions from #1724 break some console interactions by scripts - this change should fix this while reusing the --force option.

It may be discussed whether to include --no-interaction here too, as this is mentioned in the --help section of this command.

Usage:
  passport:install [options]

Options:
      ...
      --force            Overwrite keys they already exist
      ...
      -n, --no-interaction   Do not ask any interactive question
      ...

Doesn't --no-interaction do exactly what you want?
