When users see errors like
```
Duplicate plugin/preset detected.
If you'd like to use two separate instances of a plugin,
they need separate names, e.g.
plugins: [
['some-plugin', {}],
['some-plugin', {}, 'some unique name'],
]
```
It can be difficult to determine the source of the conflict, especially
in a larger build system.
This commit outputs what is known about the plugins that actually
conflict, which can be helpful for users to determine the root cause of
the conflict.

* Disallow static fields named `constructor` in a class
- Disallowed static fields named `constructor` in a class (previously only non-static were disallowed)
- Updated the text for the error for one consolidated warning, for both static and non-static fields
- Added a test
- Updated an existing test in the `flow` test suite of the parser to reflect the parse error.
Strangely, the test used to pass and started failing when inlining the `isNonstaticConstructor` method, without any changes.
In that test, `constructor` was a field, so in theory it should never have passed.
Would appreciate some feedback on this, as I'm not 100% sure if this is somehow related to Flow
* Update test262 whitelist
* Add comment and fix && operator
