Fix attribute parser to support edge-cases

[saurabhdaware]

Current parseAttribute function in src/component-parser.js file fails for cases like onload="this.rel= 'stylesheet'; this.onload=null"

In current method, we split string on spaces and consider it as separate attribute value combination and then we separate on = to find key and value.

@pantharshit00 Do you have any idea on how we can solve this? in #25 how are you adding attributes to node? can we use similar thing to get attributes from node?

[saurabhdaware]

So we can use @babel/parser to get attributes:

Apart from this we can also use @babel/parser for #24

@saurabhdaware In #25, I am just appending my attribute before > of a html opening tag.

I don't really parse anything because I don't need to parse anything.

Here is the code for that: https://github.com/pantharshit00/abell-renderer/blob/21d4a451f5e3455bf25e6518e10c6fba38afff43/src/post-compilation.js#L4

This will be fixed in https://github.com/abelljs/abell-renderer/tree/next

Hopefully fixed in #27
