Refactor TestGetPersonCreatedBounties test from using MockDB To Real DB

[elraphty]

Context

Currently, we use a mock database to test the get-user-created bounty flow

mockDb := dbMocks.NewDatabase(t)
mockHttpClient := mocks.NewHttpClient(t)
bHandler := NewBountyHandler(mockHttpClient, mockDb

Design

We want to update the mock DB to a real database spun up on a docker container and test with the DB.

bHandler := NewBountyHandler(mockClient, db.TestDB)

We will remove all the mock DB functions, and use real database DB functions used in production to test the get-created bounty flow.

e.g

mockDb.On("GetCreatedBounty, "pub-key", "1111").Return(db.NewBounty{}, errors.New("some-error")).Once()

Acceptance Criteria

• I've tested on Chrome
• I've created a test that...
• I have rebased and tested locally before submitting my PR
• I can submit a PR within 1 day of taking the bounty
