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

With this approach, we generate each time a new class and we don't expose directly the lastConfig and wireInstances variables. Then we ensure to not have some troubles with inheritances
