Activate project w/ aBLOCK payment failed

[ConanMishler]

I don't know that we've tested whether it works to activate a new project with an aBLOCK payment, so I decided to test it (even though it cost me $10 in eth gas fees to send the aBLOCK!)

Here's what I did:

1. I adjusted my DISCOUNT_ABLOCK value to 95%, then restarted the payment processor.
2. I requested a new project and got this reply:

   {
   "result": {
       "api_key": "P2kLB9PpK2Be_PzG6u97pTnVkjaVVGFChDNv2e9vm2A",
       "expiry_time": "2022-02-14 04:00:26 EST",
       "payment_amount_tier1_aablock": 64.7457,
       "payment_amount_tier1_ablock": 1.367188,
       "payment_amount_tier1_eth": 0.012199,
       "payment_amount_tier2_aablock": 369.975426,
       "payment_amount_tier2_ablock": 7.8125,
       "payment_amount_tier2_eth": 0.069709,
       "payment_avax_address": "0x56f9F4a48c4D614b51C6036BE53d7dd89Aa90a1e",
       "payment_eth_address": "0xb847f6734975D99EB90E819DfEDfE666b4A15CD0",
       "project_id": "8ff20bd2-3505-4ff2-826a-dbd6a36fa481"
   }
   }

3. I sent 1.367188 aBLOCK to 0xb847f6734975D99EB90E819DfEDfE666b4A15CD0
4. I invoked the list_projects call to see if my new project had become active. It had not become active.
5. I checked logs of exrproxy-env_eth_payment_api_1 container and found error messages like this:

   This was on my VPS4 if you want to login and poke around.

This issue seems to be fixed by https://github.com/blocknetdx/eth-payment-processor/pull/23. However, I want to test aBLOCK payments again after ETH payments are working, just to confirm aBLOCK payments still work.
