* Fix require-unicode-regexp issues
See [`require-unicode-regexp`](https://eslint.org/docs/rules/require-unicode-regexp) for more information.
This change enables `require-unicode-regexp` and fixes the issues raised by the rule.
* Remove case-insensitive flag from regexps
* Add `react/no-unused-prop-types` rule
All detected unused prop types have been removed. I have attempted to
ensure these props are no longer passed in either.
* Update handling of props to avoid false positive lint errors
These cases were detected by `react/no-unused-prop-types` as being
unused props, even though they were used. These minor adjustments
prevent them from being flagged as errors.
* Update unit tests
Many of these tests were just checking that specific props were passed
from containers or to a child component. These were deleted, as I can't
imagine how they'd be useful.
* Disable `react/no-unused-prop-types` in `componentWillReceiveProps
The rule `react/no-unused-prop-types` doesn't seem to be detecting
props used within `UNSAFE_componentWillReceiveProps`. The two cases
have been disabled temporarily until we can replace these unsafe
lifecycle functions.
* 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
