XMLRPC always interacts with database "xwikitest"

ConfluenceRpcHandler uses BaseRpcHandler.getXWikiContext() to obtain a context before retrieving or storing a page.

But BaseRpcHandler.getXWikiContext() initially obtains the context with Utils.prepareContext(), then calls:

context.setDatabase("xwikitest");

(see BaseRpcHandler.java line 60).

Consequently, XMLRPC calls affect the xwikitest database, or fail if it does not exist.
