Title: BUG: integrate: odeint crashed when only a single time point was given.

When only a single time point was given along with the argument
full_output=True, a KeyError was raised because the _msgs dict
didn't have the key 1 (the 'istate' value returned by the Fortran
solver when no work was done).

Closes gh-4282.
