Crashes on tidying all tabs of current window

[rxw1]

Crashes when clicking "Tidy n tabs". The tidytab dashboard is then the last open tab and doesn't load/stays white. ... Chrome's "Collect Errors" feature pointed to the store at line 189 where we hydrate "whenever we come back to the dashboard":

tidytab/app/store/index.js

Lines 188 to 191 in e698609

	chrome.tabs && chrome.tabs.onHighlighted.addListener(changedWindow => {
	if (changedWindow.tabIds[0] !== currentTab.id) return
	store.dispatch('HYDRATE_STATE')
	})

@rwilhelm Thanks for the issue! When did this start?
