fix: a PERMIT2_TRANSFER_FROM shows the swap's unknown first take beside its figure (closes #634)

When the step that sets the input side states no amount, a
PERMIT2_TRANSFER_FROM of the same token still showed its own figure,
which was then the only amount of that token on the screen. The rule
that adds the line saying the first take is not known now also applies
when such a move gives a figure of that token, before or after the
swap step. A move of another token, and a move into the router, read as
before.
