Fix/broken cli

[bugalot]

This PR aims at fixing the render command of the CLI.

• It includes an update of library wp-cli/php-cli-tools to version 0.11.22.
• It also include a fix for a previous change that made the render command broken.
• Makes possible to use relative paths as CLI argument.

In order to test, invoke from CLI the following command which should not return any error.

./bin/qtisdk render -df --source test/samples/ims/items/2_1_1/choice.xml --flavour goldilocks
