fix(scully-plugin-puppeteer): correctly track requests in bare project (#1610)

Previously, instead of adding/removing each request from the `requests`
set, the set itself was added/removed. Since `Set` deduplicates its
values, it would always contain just one item (regardless of how many
requests would be pending) and it would be emptied once the first
request was completed.

This commit fixes this by adding/removing the actual request to/from the
`requests` set.
