Write tests for bot-detector

[talentlessguy]

Write tests for @tinyhttp/bot-detector using supertest-fetch (that is used in other tests)

The module is quite small, so a little things have to be tested:

• It doesn't identify browser UserAgent as a bot
• It identifies Google crawler as a bot
• it identifies node request as a bot

@talentlessguy Can you please assign this to me? Thanks!

@aneeshrelan done

@talentlessguy For the 3rd task, "it doesn't identify node request as a bot", I'm not quite sure if I get this correctly, do we mean the request generated by the supertest-fetch? If yes, the user-agent comes out to be node-fetch/1.0 (+https://github.com/bitinn/node-fetch) which is being termed as a bot by the middleware

[talentlessguy]

@aneeshrelan my bad, it should identify as a bot (fixed the issue checklist now)

No worries. Have put up #112 to add tests
