Fixed issue #125: Components failed within the table.

I created issue #125 earlier in this month.

I debugged the code and here is my solution :)

I came across this issue with @PreserveOnRefresh annotated UI; when FilterTable had Label component it's text content disappeared when browser was refreshed,

This also seemed to cause an issue with TestBench; it seems that when using v8 version of FilterTable TestBench queries are unable to locate any components inside FilterTable: e.g. testBenchWrappedFilterTable.$(AbstractComponentElement.class).all(); returned empty list.

I compiled addon from lordmikefin's branch and this seemed to fix both of my issues.
