fix: plugin custom inspector tab hidden by display:none

In TabMgr.render(), the container div's className (including
util.getHide(hideAll)) was evaluated before props.tabs.map() ran.
Since hideAll was still its initial value true at that point, the
container always carried the 'hide' class (display:none), making all
plugin custom inspector tabs (declared via whistleConfig.inspectorsTab)
render but remain invisible.

Evaluate getHide() after the map() callback has corrected hideAll,
restoring the 2.10.7 semantics.
