This reverts commit f30d261e69.
The custom HD path option was found to be unsafe to use, because the
displayed list of accounts would differ depending on which application
was open on the Ledger device. Essentially Ledger was accepting invalid
inputs, and returning junk responses.
This was too dangerous to ship, as it could leave users with an account
that they can't reliably recover. If we don't know how the derivation
is happening, then allowing this import puts our users at risk of
losing funds.
We can re-introduce this functionality after adding validation to
ensure that we only allow inputs that are handled correctly by Ledger.
* 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.
* eslint: Check for unused function arguments
* eslint: Ignore unused '_' in argument list
Also allow any number of '_' e.g., '__' or '___' which is to be used sparingly
* Remove and rename unused arguments
