Cache evict not working with a custom key

[mkobel]

Caching and eviction does not work with the following example:

@Cacheable(value = 'basic', key = { key })
def doSomething(String key)  { ... }
@CacheEvict(value = 'basic', key = { key } )
def evictCache(String key) { .. }

According to my checks the problem is the@EqualsAndHashCode annotation creates a comparison where the method name is also part of the key. Therefore tha evict call cannot invalidate a cache entry.
The old manual implementation causes the same problem.
Therefore I modified the old manual implementation to skip the method name comparison if the provided keys are identical.
This is not a very nice solution but it solved the problem in my use cases.
A improved implementation might be tested using the added integration tests.

I assume the issue #46 is related to this problem.
