Fix escrow proto E2E #3517

Description

closes: #XXXX

We were getting this error

panic: invalid Go type math.Int for field ibc.applications.transfer.v1.QueryTotalEscrowForDenomResponse.amount [recovered]
        panic: invalid Go type math.Int for field ibc.applications.transfer.v1.QueryTotalEscrowForDenomResponse.amount

In our E2E tests. This PR is being used to debug this proto issue.

By making the Amount field a string we can serialize it properly.

EDIT: After discussion with @colin-axner , we decided that an sdk.Coin makes more sense and will be less confusing. Serialization works as expected with this type.

@mark-rushakoff provided the following insight to help debug the problem. Thank you!

=================================================================

The SDK is using gogo/proto (by way of our fork, https://github.com/cosmos/gogoproto). The TLDR is incompatibilities with gogoproto and official google.golang.org/protobuf.

The one I was running into was just a plain sdk.Coin. It uses a custom type, with the gogoproto.customtype option, to specify sdkmath.Int for the Amount field.

We tell it to serialize on the wire as a string (effectively (*big.Int).String(). But the gogoproto-generated struct still uses a sdkmath.Int field.

I think the correct answer here is:

Define your new message with a string field, not a math.Int customtype
Use plain google.golang.org/protobuf to generate the Go types
Add an “application layer” wrapper struct that contains the protobuf type, that exposes a sdkmath.Int by parsing the underlying protobuf struct’s string field

Thank you for the fix, @chatton; and thank you @mark-rushakoff for the insight that got us here!

I need this is in draft yet, but I just left a couple of suggestions. If the test pass, I am good going with this direction.

 	return &types.QueryTotalEscrowForDenomResponse{
-		Amount: denomAmount,


If we want to return a string, we can just do denomAmount.String(), right?

yeah this would be a bit nicer, I will play with this idea

 			} else {
-				suite.Require().PanicsWithValue("amount cannot be negative: -1", func() {
-					suite.chainA.GetSimApp().TransferKeeper.SetTotalEscrowForDenom(ctx, denom, expAmount)
+				suite.Require().PanicsWithError("negative coin amount: -1", func() {


the panic now happens in the sdk.NewCoin function instead.

if the original behaviour is desirable, we can create a coin literal instead of using the NewCoin function.
