Fix unit tests

Description

Unit tests should have been a mandatory thing before I even released FeniXCLI, while I did have tests I had plenty of issues I feel I did not want to figure out. Well, it's never too late I guess. This MR is to fix all unit tests so that we have a base set of test to run in the CI and for each MR. Future fixes will benefit from this and should improve the stability of FeniXCLI.

• All unit tests will be re-written to be CI environment friendly.
• All tests will have to pass 100% before a merge is possible.
• Some modules don't throw errors correctly this causes AVA unit tests to fail, these modules will need to be updated.
