fix crash when translate infobar is instantiated with Translating state
fix crash when translate infobar is instantiated with Translating state

translate infobar was expected to always be instantiated with BeforeTranslate state, but if connection is slow and infobar remains at Translating state when user switches to another tab then switches back to the "Translating" tab, all controls need to be created.

BUG=36812
TEST=On a slow connection, open a page that shows translate infobar, click to translate; while it's still translating, switch to another tab then switch back to the translating tab, it shouldn't crash.
