QBFT tests leftovers - Commit, Controller - Decided, Prepare, Proposal, Round-Change

[MatheusFranco99]

Tests

Commit

• Decided full data
• Invalid full data - Since the commit validation doesn't check the FullData field, it produces no error. Should I include a check, discard this test or just leave it?
• Valid full data - Commit validation doesn't check the FullData field, so why this test?

Controller - Decided

• Valid full data

Prepare

• Duplicate message quorum
• Set prepared full data

Proposal

• Valid full data

Round Change

• Invalid Justification Full Data
• Valid Justification Full Data

The test "Set prepared full data" was dropped because it's already tested in the happy flow test.
