  /**
   * This method is responsible for locating the correct plugin to use for a named command id
   * It searches the {Config} registered commands to match either the raw command id or the command alias
   * It is possible that more than one command will be found. This is due the ability of two distinct plugins to
   * create the same command or command alias.
   *
   * In the case of more than one found command, the function will select the command based on the order in which
   * the plugin is included in the package.json `oclif.plugins` list. The command that occurs first in the list
   * is selected as the command to run.
   *
   * Commands can also be present from either an install or a link. When a command is one of these and a core plugin
   * is present, this function defers to the core plugin.
   *
   * If there is not a core plugin command present, this function will return the first
   * plugin as discovered (will not change the order)
   *
   * @param commands commands to determine the priority of
