Arch Linux

Description:

Installing only woob without python-rich makes woob unusable:

```
~ $ pacman -Qq python-rich
error: package 'python-rich' was not found
1 ~ $ woob --help
usage: woob [--version] <command> [<args>]

Use one of this commands:
bands (unable to load: No module named 'woob_applications')
bank (unable to load: No module named 'woob_applications')
[SNIP]
For more information about a command, use:
$ man woob-<command>
or
$ woob <command> --help
1 ~ $ woob bank

```

Additional info:
* woob 3.6-1
* installing python-rich fixes the issue
* only installing python-colorama (woob optdepend) doesn't fix the issue

Steps to reproduce:

```
pacman -Syu woob
pacman -Qq python-rich || woob --help
```
