Change ending braces styles for JSX

[DmitryKorlas]

To improving a git-history, we approve a guide changes regarding to ending braces style on multi-line JSX tags. Ending braces should always require a new line.

Scope:

1. adjust guide examples and move from this approach:

<MyAwesomeComponent
    baz
    foo={bar}>
    <ListOfThings />
</MyAwesomeComponent>

to this one:

<MyAwesomeComponent
    baz
    foo={bar}
>
    <ListOfThings />
</MyAwesomeComponent>    

2. adjust corresponded eslint rule

@DmitryKorlas, could you move baz to the end of properties definition?
It will be more readable.

I guess it's out of scope of this particular issue and good point to specify how we prefer to use it. It could be controlled by this rule
