Disable jetpack sync during REST requests

[allendav]

Fixes #27

To test:

• Use a tool like Postman to create a product using the REST API
• Note the horribly long creation time (e.g. approx 5 seconds)
• Install this branch
• Create another product
• Note the wonderfully short creation time (e.g. approx 2 seconds)
• Profit!

Note: Bumps version to 0.7.0 also

This is night and day. Thanks for a quick fix!

I don't see any issues with the code. But I'm having some trouble seeing much improvements when testing :(. I'm not sure if I'm doing anything wrong, but I installed the new version, generated some keys, and did a simple POST to products from Postman.

On justin-devstore-at.blog, an Atomic site, I'm getting around 5 seconds with 0.6 of the plugin, and the same with 0.7 of the plugin. A few times I got less than 2, but I was able to get that in both cases occasionally. justin-devstore-at.blog doesn't have any additional plugins installed except for the ones WordPress.com & the Store setup add.

On wootest.mystagingwebsite.com I am getting sub 2 seconds for both versions.

It seems like 0.7 might be slightly faster, but I'm definitely not getting any huge improvements. It could just be me, or something else -- especially if you and others are definitely seeing a difference. Let me know if I can provide any more info.

Wait, that's true, it's not working for me either. The last time I tried it I may have gotten lucky, I got a couple of less-than-1-second requests in a row and I assumed it was working.

I've added some logging and REST_REQUEST is not defined.

I added some debug right before the return:

echo 'defined? ' . defined( 'REST_REQUEST' );
echo 'REST_REQUEST ' . REST_REQUEST;
echo 'sender_should_load: ' . $sender_should_load;

defined? false 
REST_REQUEST REST_REQUEST
sender_should_load: 1

Posting this from Slack:

from @DanReyLop

The jetpack_sync_sender_should_load filter is called in init, so at that point the REST_REQUEST constant isn't defined yet. This is gonna be more hacky than it should

I suggest maybe checking REQUEST_URI to see if it contains /wc/v3? That is the only idea I have. It's a bit hackier, but should still get the job done.

[allendav]

Fixing this now. I only did 3 requests and they all came in at 2 seconds. I'll run the automated tests after fixing it to look at the request uri instead and make sure it is consistently better then

Looks good. And is working consistently for me now. Definitely much much faster.
