Revert "[Fleet][Cloud] Enrollment token table may show an empty last …

…page elastic#167663 (elastic#188049)" (elastic#194343)

## Summary

Resolves elastic#194339.

This PR reverts elastic#188049 as it inadvertently broke pagination of the
enrollment tokens page. This means that elastic#167663 will need to be
re-opened and fixed in a different way.
