Context

Split CLI end-to-end test in a dedicated module. The benefits are:

• These tests cannot be confused with unit tests anymore
• The application module information are tested

What has changed?

Main Changes

• Split cli from cli-tests

Side effects

• core : Sort dictionary provider listing for reproducibility (otherwise it is the order in which the dictionary providers are loaded, which is not stable).

Others

• gui-tests: Minor build file simplification
