fix(Output): use default HTML log name if '-hl' CLI parameter was last

[miltolstoy]

The argument parser works differently depending on a CLI parameter position.
universum -hl ${other_params} -> settings.html_log == "universum_log.html"
universum ${other_params} -hl -> settings.html_log == "default"

Fix this to have a proper HTML log name regardless of CLI parameter position.
Resolves #711

[i-keliukh]

In the description the "Output" should be lowercase.
However, this doesn't really matter because the fix should be generic to fix both issues #703 and #711.

The real source of these bugs is located in _add_default_parser function in

Universum/universum/lib/module_arguments.py

Lines 136 to 147 in 96cb237

	def _add_default_parser(self, args):
	subparsers_action = self._get_subparsers_action()
	if not subparsers_action:
	return
	if not self._needs_default_parser(subparsers_action, args):
	return
	default = "default"
	subparsers_action.add_parser(default)
	args.insert(len(args), default)

Dropping this review because a more general fix is needed.
The same issue exists for other CLI arguments as well - #703. A more high-level CLI parser fix is required.
