INT-2439 PollerParser adviceChain.add(customBean)

Browse Source 
Fix PollerParser#configureAdviceChain for adding 'customBeanDefinition' into 'adviceChain' List.
PollerParserTests: adding <tx:advice> as customElement into poller's <advice-chain>.

Commit is mostly parser tidy-up. The crux of the fix is to add the
missing call to adviceChain.add().
