feat: provide reset last config method

[rochejul]

Related to issue #71 , this PR contains the ability for each adapter to have a resetLastConfig method.

This pr contains:

• Add on the base adapter the method
• Add tests for each adapters
• Refactor the adapters' inheritance

I needed to revisit the adapters' inheritance because for some inheritance troubles, the last Apex use case fails when we test the getLastConfig:

const cases = [
    // Works
    {
        testName: 'new api (via createApexTestWireAdapter)',
        adapter: ApexMethod,
        adapterName: 'ApexMethod',
    },
    // Works
    {
        testName: 'legacy api (registerApexTestWireAdapter) used with legacy adapter mock',
        adapter: registerApexTestWireAdapter(LegacyApexMethod),
        adapterName: 'LegacyApexMethod',
    },
    // Fails
    {
        testName: 'legacy api (registerApexTestWireAdapter) used with new adapter mock',
        adapter: registerApexTestWireAdapter(ApexMethod),
        adapterName: 'ApexMethod',
    },
];

I have the feeling the case n°2 mutate the adapter and then when we call the restLastConfig on it, the next calls of getLastConfig will fail.

With the refactoring, everything works now
