[bug] Disallow following/blocking yourself

[autumnull]

Describe the bug with a clear and concise description of what the bug is.

It's currently possible for an authenticated user to follow/block themself. I feel like this is weird behavior and shouldn't be possible.

What's your GoToSocial Version?

v0.3.6

GoToSocial Arch

armv7 Binary

What happened?

submitting an api request to /api/v1/accounts/{id}/follow (or .../block) with the currently authenticated user's id returns a relationship saying that you have followed/blocked yourself.

What you expected to happen?

should probably return a Error 406 (not acceptable) ?

How to reproduce it?

get an oauth token for an account, submit an api request as described above to the same account you auth'd with.

Anything else we need to know?
