This reworks the plugin API such that:
- Unable to register a command with unknown wrap-options
- `TypeError` raised for wrap-option type mistakes
- Remove the `overWrite` option (it's unused, probably safest to not
expose for now)
- `cmdOptions` defaults to `null` instead of `false` for type
consistency (no change to default behavior)
- Move `pipeMethods` logic into `_register`, since it makes more sense
there
This is not expected to have any effect on existing plugins.
This updates tests for `AVA` 19.0.0+.
`AVA` 0.18.0 has a breaking change which changes the current working directory
for tests. As a result, we need to change 'resources' -> 'test/resources' (and
similar path changes).
`AVA` 0.19.0 has a breaking change that all tests must run at least one assert.
This breaking change was already resolved by #746, so no change was necessary in
this PR.
This updates to `AVA` 0.21.0, since there are no other breaking changes.
