fix: ensure Give blocks are compatible with latest Gutenberg

[Sidsector9]

Current Behavior

Currently none of the Give blocks work with Gutenberg 3.8.0 since Give is using certain JS functions which are deprecated in the latest Gutenberg version.

Expected Behavior

I expect all the Give Blocks to work with the latest Gutenberg version.

Steps to Reproduce

1. Install Gutenberg 3.8.0
2. Try to add any of the Give Blocks

None of the blocks show up.

Acceptance Criteria

• Make Give Blocks compatible with latest Gutenberg version.
• Test all the Give Blocks.

Just came here to make this issue myself.

Gutenberg 3.8.0 has deprecated the withAPIData function and replaced it with withSelect.

Implementation of withSelect requires the understanding of JavaScript's Promises, Generator Functions, yield expression and react-redux.

I'm facing a problem resolving the asynchronous response of wp.api.collections.Give_forms() to get the Form List added to the Form Block. Once this is fixed, this PR will be merge-ready.

Donor Wall and Form Grid Blocks are fixed and compatible with Gutenberg 3.8.0

I have discussed this with @ravinderk and he will be looking into this.

@ravinderk WordPress 5.0 Beta 1 has released, so please make sure you are using it when developing the Give blocks. https://wordpress.org/news/2018/10/wordpress-5-0-beta-1/

After discussion with @ravinderk we are closing this in favor of a new issue with acceptance criteria relative to WP 5.0 Beta.
