HPCC-9301 Dojo 1.9 + Chrome + GraphControl Disappearing

Dojo 1.9 introduced a "_wrapper" <div> around each tab container pane.  Updated
"GraphControl.watchStyleChange" to take this into consideration.

Removed the "chrome" only condition in "GraphControl.watchSelect" as they are
also causing visual artifacts in IE10 (also introduced in dojo 1.9).

Fixes HPCC-9301
