#15298: Two versions of QQ(sqrt{-1}) upon startup

We have two copies upon startup:
{{{
sage: import gc
sage: Ks=[K for K in gc.get_objects() if
....:
isinstance(K,sage.rings.number_field.number_field.NumberField_quadratic)]
sage: [latex(k.0) for k in Ks]
[i, \sqrt{-1}]
}}}
I suspect they are coming from
`symbolic/pynac.pyx:2046 (in init_pynac_I)`
{{{
K = QuadraticField(-1, 'I', embedding=CC.gen(), latex_name='i')
}}}
and from `rings/qqbar.py:7699 (in _init_qqbar)`
{{{
QQbar_I_nf = QuadraticField(-1, 'I', embedding=CC.gen())
}}}
Should we perhaps both give them the same latex name so that these can be
the same field?
