fix a couple of flaky tests (#11100)

This fixes the following flaky tests:

- `TestHosts/LoadHostByOrbitNodeKey`
- `TestIntegrationsEnterprise/TestListSoftware`
- `TestHosts/ListStatus`

I couldn't figure out what's wrong with `TestScanVulnerabilities` which
is also randomly failing, and it's super slow to run (since it has to
download assets from GitHub) maybe @juan-fdz-hawa can spot it?
