Wrap SerializationException thrown on store internal method

Currently we have code like this:

```java
try {
byte[] value = chronicleMap.get(key);
LinkedList list;
list = value == null ? new LinkedList<>() : SerializationUtils.deserialize(value); // <- can throw
for (byte[] v : values) {
list.addFirst(new BytesValue(v));
}
chronicleMap.put(key, SerializationUtils.serialize(list)); // <- can throw
return list.size();
} finally {
lock.unlock();
}
```

From 2 places the same exception can be thrown but only 1 of them indicates client error.
Should create `try/catch` and wrap the thrown exception.

Related to #74

Start by reading the store internal method containing the two SerializationUtils calls, then review related issue #74 for context. Trace both serialization failure paths and verify that the client-error path wraps SerializationException while the other path retains its intended behavior.
