4byte fallback (#6551)
* Adds 4byte registry fallback to getMethodData() (#6435) * Adds fetchWithCache to guard against unnecessary API calls * Add custom fetch wrapper with abort on timeout * Use opts and cacheRefreshTime in fetch-with-cache util * Use custom fetch wrapper with timeout for fetch-with-cache * Improve contract method data fetching (#6623) * Remove async call from getTransactionActionKey() * Stop blocking confirm screen rendering on method data loading, and base screen route on transactionCategory * Remove use of withMethodData, fix use of knownMethodData, in relation to transaction-list-item.component * Load data contract method data progressively, making it non-blocking; requires simplifying conf-tx-base lifecycle logic. * Allow editing of gas price while loading on the confirm screen. * Fix transactionAction component and its unit tests. * Fix confirm transaction components for cases of route transitions within metamask. * Only call toString on id if truthy in getNavigateTxData() * Fix knownMethodData retrieval and data fetching from fourbyte
