Crash fix.

We never reset |tab_contents_| to NULL anywhere (and indeed we can't,
even in ReleasePreviewContents(), because browser.cc accesses it). We
were protected from acccessing a dangling tab_contents_ before, due to
the is_active() check that preceded a call to PrepareForCommit(). That
was removed in http://crrev.com/105664 however; hence this fix.
