* Add failing test case for object rest after array rest.
Discovered while upgrading https://github.com/meteor/babel to Babel 7.
The error is:
1) babel-plugin-transform-object-rest-spread/object rest with array rest:
TypeError: /Users/ben/dev/babel/packages/babel-plugin-transform-object-rest-spread/test/fixtures/object-rest/with-array-rest/actual.js: Property id of VariableDeclarator expected node to be of a type ["LVal"] but instead got null

* Fix object rest following array rest. (#6213)
* Avoid treating array ...rest elements as object ...rest properties.
* Also avoid treating ...rest parameters as object ...rest properties.
Returning early if the parent was an ArrayPattern was not quite enough,
since a RestElement can appear as a parameter in a Function as well.
* Move RestElement parent check earlier in visitor method.
* Don't merge test options.
Particularly, I don't want `lodash/merge` to merge my specific plugins
with the general test plugins. It led to odd behavior where I could
enable a loose transform in my specific test, just to have it overridden
by the test fixture's general options.
* Need options
* Remove whitespace generation and rely on default printing
Changes to printing:
* Add newline after last empty SwitchCase
* Add newlines around block comments if they are non-flow comments or contain newlines
* Fix a few more fixtures
Only the first for-await was correctly printed all subsequent for-await statements
where printed as for-of as the variable op was changed inside the buildForXStatement
