Subject: [PATCH] fix: pull_sha return value when no pull request

Pronto::Github#pull throws error when the PR cannot be found,
thus `pull[:head][:sha] if pull` makes no sense (it exists or throws)

We fix this by catching Pronto::Error (thrown when PR cannot be found in
Pronto::GithubPull#pull_by_id, Pronto::GithubPull#pull_by_branch or
Pronto::GithubPull#pull_by_commit) and return nil.
