When add a bounty, if someone is assigned just send to assigned user

[alexanmtz]

When a user is assigned and someone adds funds to that issue, notify interested users if nobody is assigned, or that user assigned if he's currently assigned.

Why

We want to notify users to let us know that a bounty was added.

Level

Beginner

Current behavior

Part of this feature, that sends a notification to all users when a payment is done successfully, is commented, so you should continue the work to implement as our requirements.

Expected behavior

If there's a user assigned, it should send to that assigned user a notification that is already implemented and commented on the code.

Screenshots

How to reproduce the user scenario

• Create a user
• Import an issue
• Create another user
• Apply to work on that issue
• Log with the first user
• Add a bounty (card 424242424242424242)
• The second user should receive a notification that an issue was added

What you will need to complete this issue

Stripe development keys in order to create a local payment and Sendgrid to be able to send emails, and you will receive these keys once you're assigned.
