[AF] Make Android label in keyboard accessory consistent with iOS.

This applies to labels for credit card suggestions when the credit card
number appears in the label.

On Android (dropdown and keyboard accessory), a suggestion appears as

dropdown:
Caitlin Fischer
Visa  ••••1234

keyboard accessory:
Caitlin Fischer  Visa  ••••1234

After this CL is merged, Android keyboard accessory labels will be
shown as Caitlin Fischer  ••••1234. Note that the network or bank name
is removed.
