pyeantic fails to parse rational field

[saraedum]

Currently, the following does not work:

sage: from pyeantic import RealEmbeddedNumberField
sage: RealEmbeddedNumberField(QQ).renf
NumberField(x-1, 1.000000000000000000000000000000000000000000000000000000000000000)
sage: K = RealEmbeddedNumberField(QQ).renf
sage: RealEmbeddedNumberField(K)
