fix: Revert change to module bundling (#177)

* fix: Revert change to module bundling

Looks like `iife` from rollup isn't exposing agent as a global. We
need `window.PercyAgent =` not `var PercyAgent=`

* Remove `http-server` dep temporarily

`http-sever` relies on `estatic@3`, which was yanked from the npm reg
for security reasons. This broke CI
