fix: convertRunRequest: std.MemPackage needs a Name (#206)

After the recent "crossing" changes, `TestRunSingle_Integration`, etc.
were updated so that `std.MemPackage` [needs a
`Name`](https://github.com/gnolang/gno/blob/9b763e9b11a55be644f33208840ad2e8f88336af/gno.land/pkg/gnoclient/integration_test.go#L340-L341)
so that the back end handler can use it to set the `Path`. We need to do
the same. Without this, calling `Run` results in an "invalid path"
error.
