Fix confirm token transaction amount display (#7081)
The token amount displayed when confirming a token transaction was
wrongly being converted to a string in the container. As a result, the
conversion into the user's preferred currency would fail.

A default value of '0' was added for the token amount as well, to
prevent `undefined` from being rendered as the value. Really the value
should never be undefined, but it was rather difficult to handle that
case without a deeper investigation into how it might occur. The 0
default is consistent with existing rendering logic.
