When contract addresses that are not ERC-20 or ERC-721 were input, the token would be allowed to be added and would crash the app.
In addition, when an ERC-20 contract was deployed without a name and symbol, “Invalid ERC-20 address” would appear.
This PR adds error checking from the token detail lookup and reports the error back to the user in the modal. This prevents non-ERC-20/721 contracts from being able to be added to the app and prevents a crash.
There are some inconcistencies in the application when it comes to
button UI elements because we're using `StatusButton` in some places,
in other we use `StyledButton`. The latter is the original
component we've created when we started out building Status
Desktop, but is planned to be removed entirely in favour of
`StatusButton`.
This commit replaces the usages of `StyledButton` with `StatusButton`
