 Fixed a memory leak in ManagerMessageHandler.

+The SDK now throws `InvalidArgumentException: Failed to parse connection string` if the connection string has a syntax error.
+For example, the following connection string is malformed, because the `couchbase://` part is repeated:
+`couchbase://foo.example.com,couchbase://bar.example.com`.
+The correct way to include multiple addresses in a connection string is to specify the scheme only once, and to join addresses with commas, like:
+`couchbase://foo.example.com,bar.example.com`
