When the BFG object map file is in object storage (i.e., uploads in
general are placed into object storage), we get an instance of the
Gitlab::HttpIO class. This doesn't behave as expected when you try to
read past EOF, so we need to explicitly check for this condition to
avoid ending up in a tight loop around io.read

Resolve a transient failure in MWPS feature spec

Closes gitlab-ee#6770

See merge request gitlab-org/gitlab-ce!23838

Sometimes due to a slow request to load the version check image, the
placeholder image data was still being seen, resulting in this failure:

    expected "data:image/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==" to end with "/version-check-url"

Now we check the `data-src` attribute, which allows us to remove the
`:js` metadata.

This commit also removes a redundant test, which was just ensuring that
the selector we were already using in the other test is visible. If this
test were failing, the other one would always fail too, so it was
pointless.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/55372

All of these methods are stateless, there was no point to have them as
instance methods.

Mostly this allows us to remove an `allow_any_instance_of` usage.

Because we removed rails 4 support, this document is not needed
anymore.
