Remove unnecessary bottom border Android from default style

Version

Tell us which versions you are using:

• tcomb-form-native v0.6.1
• react-native v0.34.0

Every TextInput has unnecessary bottom border after RN34

we should set underlineColorAndroid='transparent' as the default

But it should. This is what I have in my options as well:

{
        stylesheet: stylesheet,
        auto: 'none',
        fields: {
            name: {
                placeholder: 'Name',
                underlineColorAndroid: 'transparent',
            },

and it works…

I agree it shouldn’t show the line by default.
