Feature/#53 gutenberg 3 2 compatibility

[jomurgel]

Closes #53

DESCRIPTION

Resolved a couple of issues.

Updated Gutenberg to v3.2 and confirmed that the following blocks are working:

• Hero
• Call To Action
• Github Gist
• Recent Posts
• Two Column
• Users Grid

I was able to confirm that the Related Posts was our problem child. Specifically that it looks as if 3.2 introduced an issue that breaks any use of new WP_Query inside the render.php output. Tested this theory and confirmed.

Submitted an issue over on Gutenberg WordPress/gutenberg#8035 to try and maybe figure out what's going on. There are several related issues around the use of core WP functions not working—get_the_excerpt and the_excerpt use failures to name just one.

I also updated the block_get_excerpt which now works with the foreach loop — and kind of ends up fixing some logic errors.

A couple of unrelated fun facts, ACF 5.6.10 has some conflicts with the wp.hooks call which is resolved by updating to 5.7. These blocks still function as expected with 5.6.10.
