Update browser_navigator.cc to consider not being able to create browser

There are several trigger points for calling Browser::Create in
browser_navigator.cc which do not check if browser can be created for
the given profile.

Checking for possibility of browser creation is added to these cases
and a nullptr is returned if browser can't be created.
