Remove unused `network` prop (#8633)

The `Identicon` component was being passed a `network` prop, despite
not accepting a `network` prop.

A duplicate set of `token-cell` tests have also been deleted, as they
used this prop. The tests were never run, because the file was misnamed
(it needs to be named `.test.js`).
