Hubble cannot index non custom wasm events

[0xLaurenzo]

Hubble can only index custom events from cosmwasm and is unable to index attributes emitted by a default wasm event. This is caused by this comparison

const TYPE_WASM_PREFIX: &str = "wasm-";

// emitted for brevity

if !event_type.starts_with(TYPE_WASM_PREFIX)

This can already be solved by either changing the comparison to something like

const TYPE_WASM_PREFIX: &str = "wasm-";
const TYPE_WASM_EVENT: &str = "wasm";
// emitted for brevity

if !event_type.starts_with(TYPE_WASM_PREFIX) && !event_type == TYPE_WASM_EVENT

or by changing the wasm prefix like so

const TYPE_WASM_PREFIX: &str = "wasm";
// emitted for brevity

if !event_type.starts_with(TYPE_WASM_PREFIX)
