don´t panic on e2e ESIPP tests

Browse Source 
The ESIPP tests are using a function to poll an HTTP endpoint.
This function failed the framework if the request to the http endpoint
timed out, causing a panic that ginkgo couldn´t recover.

Also, this function was used inside a pollImmediate loop, so it should
return the error instead of fail.
